2.1 W hat is a radar ?

A marine radar is one of the navigation equipment installed on a ship. I t emits a radio wave in very high frequency called a microwave from its antenna and receives the reflected ra dio wa ve fr o m obj e cts o n t he se a ( e.g., o t her ships, bu oy s, a nd la nds). The rece i ve d r a di o wave is converte d into an electric signal which is displaye d on a display scree n to indicate the presence of such obj ect s. Alt h ou g h it is ve r y di fficu l t t o find ot h e r sh ips o r t he de stination coast with human eyes at night or in thick fog, a radar helps you detect objects on the sea helping you av oid danger when sailing. The ante nna turns 360 degre es a s it radiate s waves , allowin g y o u to gras p ambi en t co ndi ti ons aro und your shi p at a glan ce.

The radio wave r adi ated f r om th e anten na i s c a l led a pul se wave a nd the rada r per fo r ms transmission and reception alternately. Several hundred to several thousand pulse waves gener al l y are tran sm i tted whi l e the an tenn a r o tates o ne turn.

Antenna (Rotating)

Fig .2-1 What is a radar?

Antenna

There are many types of antennas generally used for a radar. For example, these include a parabolic antenna and a slotted-array antenna. The performance of the antenna determines that of the radar. The dominant factors are the antenna's beam width and side lobe level. The narrower the beam width, the higher the resolution of the angle direction. The lower the side lobe level, the fewer the effect of a f a l se echo.

Side lobe

A beam in one direction in which the strongest radio wave is radiated from the antenna is called the main lobe and beams in other directions are called "side lobes". The side lobe level refers to the difference in level between the largest side lobe and the main lobe.

Beam w i dth

A bea m widt h is defi ned as the widt h of t he ma i n l obe a t a n a n g le w here t he radi ated power is halved as measured from the position from which the strongest radio wave is rad i ated .

2.2 Ch aracteri st ics of Radar Wave

Radio wave s from the radar propagat e while bending slightly along the te rrestrial surface. This characteristic varies dependent on the density of the atmospheric air. The sight distance D of a ra dar ge ne ra lly is said to be approximate ly 6% longer than t he optical sight distance and is calculated using the equation below :

D (NM) = 2.22 ( h1 + h2 ) where, h1= antenna height in meters

h2= target height in meters

Targets difficult to display on screen

The intensity of the reflected wave from a target depends on the distance, height, and size of the target, as well as its material and shape. Targets constructed with FR P, w ood, or oth er l ow- r eflectanc e ma ter ials o r tho se th a t have a smal l inci den t ang le are difficult to display on a screen. Therefore, FRP and wooden ships, sandy beaches, and sandy or muddy shallows all are difficult to catch and require attention when m onito r i ng on t he s creen. Espec iall y , coa st l i nes o n th e r adar image ap pear to be pr esent mo r e ap ar t from th e shi p th an they are actuall y l o cat ed. Theref ore, i t i s importan t no t to misint er pret t he a va i lable d a ta .

Shadow zon es of r adar

Radar waves are characteristic in that they propagate straight ahead. Therefore, if the ship's smokestack or mast is locate d nea r t he a ntenna or the re is a ta ll ship or mount a i n at the side of the s h ip, su ch a n object g ene r at es a shadow be h in d it. In t hi s

case, some objects produce a complete shadow and some produce a partial shadow. In an extreme case, the shadow of an object may extend to a position far away and cannot be displayed on the screen at all. Since these shadows can be discovered when installing an antenna, the problem can be a v oided by changing t he place of ante nna insta l lat io n t o minimiz e t he sha dow. Ta r g e ts in sh a dow z o nes a r e di fficu l t t o displa y on the sc r een.

Fal s e echoes

A false echo of an actually nonexistent object may sometimes appear on the screen when sailing. The following explains the cause of each of such phenomena.

A. Ghost echoes

It somet ime s h a ppe ns tha t on e l a r g e obj e ct ne ar the sh ip appe a r s at tw o di ffe r ent bear ing s. One is th e actua l ech o an d o t her i s a g ho st echo g enerated as t he wave is rereflected from the ship's own smokestack or mast. The former appears at the correct distance and bearing on the screen and the latter appears behind the smokestack or mast. This type of false echo is also gener ated by re -reflection of wave s from bridges and quay walls other than the ship itself.

B. Multiple echoes

If th ere i s a l a r g e verti cal r eflecti ng plane n ear the ship as in the cas e when your ship passes alongside a large ship, the wave is repeatedly re flected back and forth between your ship and the other object. For this reason, two to four images appear on the screen at equal intervals in the same bea ring. A false echo that is genera ted by such multiple reflections is called multiple echoes. In this case, an image appearing at the nearest position is the real echo. Multiple echoes disappear as the ship moves away from the refle cting object or its bear ing change s. Ther e fore, it is n ot difficult to deter mine the co r r ect i mag e.

C. False echoes caused by side lobe

The radiant beam emitted from an antenna contains side lobes in directions other than th a t of t he main b ea m . S i nce th e side l ob e l evel is low, it in no way af fec t s distant targets. However, if there is a strong reflecting target near the ship, it sometimes appear a s a cir cul ar -arc f a l se ec ho on t he sc r een.

When located near large targets such as land, the ship's mast, etc. sometimes appears as a false echo of ci rcular-arc shape.

D. Dist ant fals e echoes caus ed by du ct pheno menon

Depe nding on mete orological conditions, duct pheno menon sometimes oc curs in temperature inverting layers of air. In such a case, the wave propagates erratically re a ch in g a l oca tion surpr i si ng l y fa r a wa y fr om t h e sh ip. In this case, a t a r g et pr esent at a distant location more than the radar's maximum distance range appears on the screen presenting a false echo that can be misunderstood to be present nearer than the actual positi o n. Th is ph en o men o n is attributed to the f act that sin ce echo from the distant tar get arrives late, it gets out of the p ul se repetitio n frequency and is displayed on the screen as an echo in the next frequency. If the target distance changes as you switc h o ver the d is ta nc e r ange, you c an d et er mi ne th at it is a fal se ec ho .

Since echo signals received by the radar are strong when they are coming from a short dista nce, it is dif ficult to compa re sig nal st rengt h bet wee n each re flect ed sign al. To o ver come this difficulty, signal strength is adjusted in such a way that the received signal levels coming from a short distance are lowered and those from a long distance are raised.

3.3 Determini ng P lace of In st allat ion

3.3.1 Sc anner unit

A radar's target detection capacity varies greatly depending on the fitted position of the scanner. An ideal fitting position is a location high above the ship's keel line where there is no obstacle all around the scanner. In an actu al ship, such an ideal locat ion is limited by various f actors. Therefo r e, c on sider t he f oll owi ng sug g esti ons when y ou determine the place to install the scanner:

(a) Install scanner at a position as high as possible.

The higher the installation position, the longer the radio ranging distance. Install the scanner at a position as high as possible after considering the ship's hull structure and radar maintainability.

(b) Install scanner away from smoke-stack and mast

I f the scan ner is inst al led a t t he same he ig ht as th e smoke -st ack or ma st, radar waves may be blocked, creating shadow zones or generating false echoes. Therefore, do not install the scanner at such a position.

To avoi d cre a t ing sha dow z ones or g e nerati ng fa lse echoes, inst a ll t he scanner at a position neare r t o the ship's bow away from obsta cles. When installing the scanne r on a ma st, p osit ion it i n fro nt of t he mast. (I f obst acl es cann ot be avoided for the ship's structural reasons, refer to "Shifting away from obstacles" described Page 13.)

(d) Do not install the scanner near hot or heat-generating items.

Do not install the scanner at a position where it may be subjected to smoke or hot air from smokestacks or heat from lamps.

(e) Install the scanner away from antennas of oth er equipment.

Install the scanner as much away from the antennas of a direction finder, radio transceiver, etc. as possible.

5A/250V or 125V

(5•x 20mm)

T3.15A/250V or 125V *

(5• x 20mm)

CAUTION

To eliminate the interference, install the scanner away from th e anten na of radio transceivers.

(f) Make the cable length as short as possible.

Keep the distance from the scanner to the display unit within the standard cable length of 10 m. If you use longer cable for unavoidable reasons, limit the cable length to a maximum of 30 m for RA40C and 100 m for RA41C/42C.

3.3.2 D ispla y unit

The display unit can be installed on desktop, wall surface, or ceiling. Dete rmine the place to install the display unit that is convenient for nav igation and radar opera tion after considering the following suggestions:

(a) A place where you can s ee the ship' s bow when you rai se you r face f rom t he

radar screen. (b) A plac e wh ere there is n o dir ect sun-li ght to av o id display t emperatu re up. (c) A place where there is good ventilation and minimum vibration. (d) A place where the display unit is a part m ore tha n the min im um safe dis-

tance from a magnet compass as listed in Tab.3-5 below.

3.3.3 Sh ifting away from obsta cles

! Shifting from keel line

By shifting the scanner position from the keel line to the starboard side of the ship, it is possible to move shadow zone s to the p ort side which makes it possible to keep clear vision in the bow direction. The distance to be shifted can be obtained by calculation depending on the distance from the scanner to obstacl es using the f oll owi ng equa tion:

Ls=0.4R+D/2 [m] (when R<15m) Ls=0.025R+D/2 [m] (when R>=15m)

where Ls = distance to be shifted from keel line

D = di am et er of ob stacle on keel li ne R = distance from scanner to obstacle

Obtaining sufficient dip angle

""""

Raise the scanner position so that there is a sufficient dip angle θ available between the line of sight from the scanner to the obstacle and the horizontal

line. By raising the dip angle above 5°, it is possible to prevent mid- and longdistance shadow zones. The radar cannot detect objects below the line of sight.

3.4 I nstalling S canner Unit

When you have decided the place of installa tion, install the scanner unit. I f a mou nt base like the one shown below is available, it may be easie r t o install the scanner. I f such a mount base is not ava ilable in your ship, you may install the scanner directly to the roof, etc. In s uch a cas e, p ay atten ti on to the water d r ai n tube loc ated at th e bottom of the scanner unit during installation.

Note : When the radar mast or mounting bracket has a curvature of more than 2mm, repair it o r u se s pacers.

Do not use an edge that might trap water.

Fig.3-3 Mount base

Referring to Fig.3-4, open holes in diameter of 12 mm (0.47 in.) at five locations in the mount base and use these holes to fix the scanner unit to the mount base with hexagonal bolts. (Use the template included with t his manual.) The bolts included wit h your radar equ ipment will suffice for mount base thickness of 9 to 14 mm (0.35 to 0.5 5 in.). I f the mount base is thicker or thinner than this, prepare bolts listed in Tab.3-6.

Use sealing of silicon when you prevent the bolts from becoming loose. Radome may be bro ken i f yo u use lo cking putty.

3.10 Countermeasure for El ect romagneti c Int erf erence

RA40C/41C/42C radar provides shields in the unit s and t he inte r-u nit connection cable. When the radar, however, is closely installed to radio equipment such as VHF transceiver, UHF transceiver, etc., or the radar and/or radio equipment are not sufficiently gro u nd ed to t he hu l l or sh ip' s ear t h, the radar may hap pen to c a use EM I troub le.

Followings are general procedures for reducing EMI due t o radars. When installing ra dars, refer to them, and also check the radio equipment EMI trouble with operating the radar and radio equipment.

(1) Installation Place of Radar

The display unit, scanner unit and inter-unit connection cable should be located apart from the main unit, feeder, antenna coupler and antenna of radio equipment as far as possible.

Especially, proper installation of the fee der, ante nna coupler and ante nna of ra dio equipmen t is ver y i mportant to improve E MI tro ubl e. (2) Laying Power Supply Cables

Follow ing conne cti ons A a nd B a re re commended t o r e du ce condu cti on noise ge nerated from radar. Connection C should not be used.

Connection A (Very Good)

Connection B (Good)

Connection C (Bad)

(3) Grounding

All equ i pmen t sh ould be f i rmly g r oun ded a t t he earth n earest hul l with cop per plates or braided wires.

Impr o vement Proce du re for EMI

(1 ) Co nf irm g r oun ding on the rad ar a nd r adi o equi pmen t. H oweve r , some equip ment, on

which grounding is not always necessarily, have a possibility of EMI improving w hen

taking off their gro unding. Try to take off gro unding. (2) Confirm power supply cable connections and modify to the connection A or B above. (3) Try to shift the display unit and inter-unit connection cable of radar to be apart from

radio equipment. (4) Try to shift the feeder of radio equipment to be apart from each units and the inter-

unit connection cable of radar. (5) Try to shift the antenna coupler and antenna of radio equipment to be apart from

the scanner unit and inter-unit connection cable of radar.
