SONAR SYSTEM SUMMARY

SONAR MODE

A sonar system uses the transmitter-receiver as well as an echo sounder.
An echo sounder is only able to search in one direction, down.
However a sonar has a movable transducer and therefore can freely search the entire
around a ship, not just the area directly beneath the ship.

When the sonar is not operated, the transducer is retracted.
While operating, the transducer is protruded from the hull bottom.

Echo sounder transducer Sonar transducer

An ultrasonic pulse is emitted from the transducer protruded from the hull bottom.
The sonar principle detected by the transducer is the same with the echo sounder.
However, like a searchlight, the sonar transducer sends and detects ultra-sound
beams one after another while giving relative bearing at some speed in proper ranges.
The transducer scans or trains with the step angle set at MENU.

The seabed and fish school will send a reflected echo of sound back to the ship.
In a PPI sonar, this reflection with relative bearing and range information is presented
like a radar screen.

SONAR SYSTEM SUMMARY

An echo sounder is only able to search in one direction within some beam angle, beneath
the ship. A sonar, however, can freely search the broad range, since the transducer’s
angle can be varied not only the horizontal direction but also the vertical direction.

SONAR SYSTEM SUMMARY

TILT ANGLE

The tilt angle shows the direction to which the sound
wave is emitted. The tilt angle can be set in step of 1°
from 0° to +5° (upward) to 0° to 90° (downward).

Find out the suitable tilt angle for a given depth and
detection range.

The tilt angle is of importance when working with sonar.
Refer to the illustration below. Find out the suitable tilt angle and beam coverage.
When the ship approaches B with the same tilt angle, the reflection is getting smaller
and weaker gradually and nothing appears at B position.
Without changing the tilt angle, the fish school is out of beam coverage at B position
so that no reflection appears on the screen. Set an appropriate tilt angle so that the
reflection of fish school always appears on the screen.

ＡＢ ＡＢ

SEA BOTTOM SEA BOTTOM

Choose appropriate
tilt angle to target
fish school.

The narrow tilt angle is selected for surface detection, however, if 0° is selected,
sometimes the reflection of the sea surface appears on the screen as the noise and
interferes with observation of wanted echoes.
Adjust an appropriate tilt angle to lessen the affect of sea surface reflection.

If the tilt angle is set to 0゜
the affect of sea surface
reflections appears.

BEAM COVERAGE

Set the tilt angle
wider until the
affect disappears.

The Tilt angle is also set in the Bottom Scan mode and the Echo Sounder mode.

SONAR SYSTEM SUMMARY

TILT ANGLE AND DISPLAY

In the shallow water the bottom reflection is prominent, so it is important to be able
to distinguish fish echoes from the bottom echo. Therefore the setting of the tilt angle
is important to find out the suitable tilt angle.

TILT ANGLE –40° TILT ANGLE –25° TILT ANGLE –10°

FISH SCHOOL 1

• TILT ANGLE 40° :

• TILT ANGLE 25° :

• TILT ANGLE 10° :

Fish school is just above the bottom echo so that it is
hard to discriminate fish echo from the bottom, since the
distances from fish school and from bottom are the same.

Fish school is clearly seen. Fish school is displayed
behind the bottom echo, since fish school is in the area
of weak reflection of bottom echo.

Bottom echo is weak so that fish school is easily seen.
Due to the density of fish school the strong reflection of fish
school is easily displayed on the screen.
Fish school 3 is actually in the middle layer, however it is
displayed likely to be near the bottom echo on the screen.

NOTE !---------------------------------------------------------------------------------------------------------

The explanation mentioned above is extremely general explanation, and it is
not a thing satisfying all conditions, which is different depending on the
situation of the sea and a state of the bottom of the sea, setting of sensitivity
and so on.

SONAR SYSTEM SUMMARY

BOTTOM SCAN MODE

When this mode is selected, the transmitter/
receiver does not rotate like a sonar, but
sweeps from side to side like a pendulum
when the sound wave is emitted.
The reflected echo from the sea
bottom is displayed on the screen
sequentially.

When the bottom scan mode is selected,
it sweeps from side to side in the step set
with STEP on MENU - DISP ITEM SEL.
Changing the sector angle makes it
possible to detect the wider or narrower
range as desired.

The center direction of the sounding beam
can be changed with the tilt angle.
Choose the setting of the tilt angle which
places the sector center in the middle of the
detection range.

In the bottom scan mode the detectable
direction is provided not only rightward
or leftward, but also in the direction of
360° by setting the direction of the transducer.
