SAFETY INSTRUCTIONS
CAUTION
WARNING
Do not depend on one navigation device for the navigation of the ship. The navigator must check all aids available to confirm position. Electronic aids are not a replacement for basic navigation principles and common sense.
· The ARPA automatically tracks an automatically or manually acquired radar target and calculates its course and speed, indicating them by a vector. Since the data from the auto plotter depend on the selected radar targets, the radar must be optimally tuned for use with the auto plotter, to ensure required targets will not be lost or unnecessary targets like sea returns and noise will not be acquired and tracked.
· A target is not always a landmass, reef, ship, but can also be returns from the sea surface and from clutter. As the level of clutter changes with the environment, the operator must correctly adjust the A/C SEA, A/C RAIN and GAIN controls so that the target echoes do not disappear from the radar screen.
CAUTION
The tracking accuracy is affected by the following:
· The tracking accuracy is affected by course change. One to two minutes is required to restore vectors to full accuracy after a sudden course change. (The actual amount depends on gyrocompass specifications.)
· The amount of tracking delay is inversely proportional to the relative speed of the target. Delay is on the order of 15-30 seconds for high relative speed; 30-60 seconds for low relative speed.
The data from ARPA and AIS are intended for reference purposes only.
Check all available navigation aids to determine target movement.
WARNING LABELS
Warning labels are attached to the equipment. Do not remove any label. If a label is missing or damaged, contact a FURUNO agent or dealer about replacement.
WARNING
Radiation hazard. Only qualified personnel should work inside scanner. Confirm that TX has stopped before opening scanner.

After the self-tests have completed, the bearing scale and a digital timer appear. The digital timer counts down the time necessary to warm the magnetron, which transmits the radar pulses. The time to warm the magnetron is 90 seconds for FR-8045/FR­8065 and FR-8125 radars, 180 seconds for FR-8255 radar.
After the timer reads 0:00, the STBY screen appears. The STBY screen has three types. (See paragraph 1.44.2.) The radar is ready to transmit the radar pulses. Press the STBY/TX key to transmit the radar pulses.

1.15 How to Measure the Range to a Target

You can measure the range to a target in three methods. You can use the fixed range rings, the cursor (if set to measure range and bearing) and the VRM (Variable Range Marker).
Use the fixed range rings to get a rough estimate of the range to a target. The fixed range rings are the concentric solid circles about your ship. The number of rings changes with the selected range scale. The interval of the range ring is displayed at the upper-left corner of the screen. Count the number of rings between the center of the display and the target. Check the range ring interval and measure the distance of the echo from the nearest ring.

Noise Rejector options
The wiper feature automatically reduces the brilliance of unwanted weak signals (noise, sea clutter, rain clutter, etc.) and unnecessary signals, like radar interference, to clear the picture of unnecessary echoes. The result of wiper depends on the wiper setting used and whether echo averaging is turned on or off, as described below.
Wiper 1 Wiper 2
Echo Average Off Processing content A
Echo Average On (1,2, Auto) Processing content A Processing content B
Processing content A: The brilliance of unnecessary weak echoes, like noise and ra­dar interference, is reduced to clear the picture. The difference between wiper 1 and 2 is that brilliance is lowered more slowly in 1.
Processing content B: Echo averaging is automatically turned from off to on when the wiper feature is turned on. You can see how the picture changes with the echo av­eraging turned off and turned on.
To activate the wiper feature, do the following:
1. Press the MENU key to open the menu.
2. Use S or T to select [Echo] and press the ENTER key.

2. DESCRIPTION OF RADAR

2.1 General

2.1.1 Minimum and maximum ranges

Minimum range
The minimum range is defined by the shortest distance at which, using a scale of
2
0.0625 or 0.125 nm, a target that has an echoing area of 10 m
the point that shows the antenna position.
The minimum range depends on the pulselength, antenna height, and signal process­ing (like main bang suppression and digital quantization). Use a shorter range scale as far as it gives favorable definition or clarity of picture.
The FR-8045/FR-8065/FR-8125/FR-8255 radar series meets the requirements of IEC 62252 5.14.1 (Class A).
Maximum range
is shown separate from
The maximum detection range, Rmax, changes depending on the height of the anten­na, the height of the target above the sea, the size, shape and material of the target, and the atmospheric conditions.
Under normal atmospheric conditions, the maximum range is equal or a little shorter than the optical horizon. The radar horizon is longer than the optical one by approxi­mately 6%, because of the diffraction property of the radar signal. The Rmax is shown in the following formula.
R
= 2.2 x ( h1 + h2)
max
where R h1: antenna height (m) h2: target height (m)
If the height of the antenna is 9 m and the height of the target is 16 m, the maximum radar range is;
: radar horizon (nautical miles)
max
Optical horizon
R
= 2.2 x ( 9 + 16) = 2.2 x (3 + 4) = 15.4 nm
max
Radar horizon
Note: The detection range is reduced by any precipitation (which absorbs the radar signal).

2. DESCRIPTION OF RADAR

2.1.2 Radar resolution

The bearing resolution and range resolution are important in radar resolution.
Bearing resolution
The bearing resolution is the ability of the radar to display the echoes received from two targets at the same range as the separate echoes. The bearing resolution is pro­portional to the antenna length and the wavelength.

2.1.3 Bearing accuracy

One of the most important features of the radar is how accurately the bearing of a tar­get can be measured. The accuracy of bearing measurement depends on the narrow­ness of the radar beam. The bearing taken is relative to the heading of the ship. Correct adjustment of the heading line at installation is important to get accurate bear­ings. To minimize the error when you measure the bearing of a target, put the target echo at the extreme position on the screen by selecting a suitable range.

2.1.4 Range measurement

Measurement of the range to a target is important function of the radar. There are three methods to measure range: the fixed range rings, the Variable Range Marker (VRM), and the cursor (if the cursor is set to measure range and bearing). The fixed range rings appear on the screen with a given interval and provide a rough estimate of the range to a target. The diameter of VRM is increased or decreased so that the marker touches the inner edge of the target (see paragraph 1.15.2). The VRM is a more accurate range measurement than the fixed range rings. For cursor, see section 1.13.
2. DESCRIPTION OF RADAR

2.2 False Echoes

The echo signals can appear on the screen at positions where there is no target or disappear when there are targets. These false echoes are shown below.

2.2.1 Multiple echoes

Multiple echoes occur when a transmitted pulse returns from a solid object like a large ship, bridge, or breakwater. A second, a third or more echoes can be seen on the dis­play at double, triple or other multiples of the actual range of the target as shown be­low. You can reduce and remove the multiple reflection echoes with the A/C SEA control.

2. DESCRIPTION OF RADAR

2.2.2 Sidelobe echoes

When the radar pulse is transmitted, some radiation escapes on each side of the beam, called "sidelobes”. If a target is where a target can be detected by the sidelobes as well as the mainlobe, the side echoes can be shown on both sides of the true echo at the same range. Sidelobes show normally only on short ranges and from strong tar­gets. You can reduce the sidelobes with the A/C SEA control.

2.2.3 Virtual image

A large target close your ship can appear at two positions on the screen. One of them is the true echo reflected by the target. The other is a false echo which is caused by the mirror effect of a large object on or close your ship as shown in the following figure. If your ship comes near a large metal bridge, for example, a false echo can temporarily appear on the screen.

2.2.4 Shadow sector

Funnels, stacks, masts, or derricks near the antenna interrupt the radar beam, and a non-detecting sector can occur. Radar can not detect targets within this sector.

2.3 SART (Search and Rescue Transponder)

2.3.1 SART description

A Search and Rescue Transponder (SART) responds to any X-band (3 cm) radar with­in a range of approximately 8 nm. Each radar pulse received causes the SART to transmit a response which is swept continuously across the complete radar frequency band.

2.3.2 General remarks on receiving SART

SART range errors
When the SART is at a range greater than approximately 1 nm, the first dot is dis­played at 0.64 nm past the true position of the SART. When the range closes so that the fast-sweep responses are also seen, the first range echoes are displayed at 150 m past the true position.
Range scale
When you find the SART position, do as follows:
1. Use the RANGE key to set the range scale to 6 nm or 12 nm.
2. Turn off [A/C Auto].
3. Turn off [Int Rejector].
SART display
To display only the SART echo clearly on the radar screen, reduce the tuning on man­ual mode. The normal radar echoes get weak, but the SART echoes remain. Your ship comes near the SART, the arc for the SART display becomes larger. Most of the radar screen becomes fuzzy. Adjust the A/C SEA and GAIN controls to display the neces­sary screen.

2.4 RACON

The RACON is a RAdar beaCON which sends radar-receivable signals in the radar frequency spectrum (X- or S-band). There are several signal formats; in general, the RACON signal appears on the radar screen as an echo in the shape of a rectangle originating at a point just past the position of the radar beacon. It has a Morse coded pattern. Note that the position on the radar display is not accurate.

3. ARPA OPERATION

CAUTION
CAUTION
The Automatic Radar Plotter ARP-11 (option) manually or automatically acquires and tracks ten targets. When a target is acquired automatically or manually, a target is au­tomatically tracked within 0.1 to 16 nm.

3.1 Precautions for Use

CAUTION
Do not depend on one navigation device for the navigation of the ship. The navigator must check all aids available to confirm position. Electronic aids are not a replacement for basic navigation principles and common sense.
· The ARPA automatically tracks an automatically or manually acquired radar target and calculates its course and speed, indicating them by a vector. Since the data from the auto plotter depend on the selected radar targets, the radar must be optimally tuned for use with the auto plotter, to ensure required targets will not be lost or unnecessary targets like sea returns and noise will not be acquired and tracked.
· A target is not always a landmass, reef, ship, but can be returns from the sea surface and clutter. As the level of clutter changes with the environment, the operator must correctly adjust the A/C SEA, A/C RAIN and GAIN controls so that the target echoes do not disappear from the radar screen.
CAUTION
The tracking accuracy is affected by the following:
· The tracking accuracy is affected by course change. One to two minutes is required to restore vectors to full accuracy after a sudden course change. (The actual amount depends on gyrocompass specifications.)
· The amount of tracking delay is inversely proportional to the relative speed of the target. Delay is on the order of 15-30 seconds for high relative speed; 30-60 seconds for low relative speed.
The display accuracy is affected by the following:
· Echo intensity
· Pulse width of radar transmission
· Radar bearing error
· Gyrocompass error
· Course change (your ship or target)

3.2 Controls for Use with ARPA

ENTER: Acquire the cursor-selected target. Display data for tracked target (in the data
box at the bottom of the screen). CANCEL/HL OFF: Remove data of cursor-selected tracked target from the data box. Stop tracking the cursor-selected target (when its data is not displayed in the data box).

4.12 CPA/TCPA Alarm

Set CPA (Closest Point of Approach) alarm range and TCPA (predicted Time to CPA) alarm time to alert you to targets that can be on a collision course. When CPA and TCPA of any AIS target (including a sleeping target) become less than the preset CPA and TCPA alarm settings, the audio alarm sounds. The alarm message "COLLISION" appears. The target symbol changes to a dangerous target symbol (red) and its vector flashes. You can stop the audio alarm and flashing with any key. The dangerous target symbol is displayed until the AIS target is not in the CPA and TCPA alarm setting. The AIS continuously monitors CPA and TCPA of all AIS targets.
This feature helps identify the targets that can be on a collision course.
