Is the SART a transmitter or a receiver?
It is a transponder
Transmitter and receiver, receiving radar signals and transmits its signals

How does SART transpond to the navigational radar?
When SART is interrogated by RADAR signals, SART is activated.
(first signal – a rapid of 0.4 microseconds sweep
The first signal is followed by-
A 7.5 microseconds sweep
And-
This will be repeated 12 times.
This will cause – a series of 12 blips/arcs/circles on RADAR.

When the SART is 5 mls away from radar, what is the indication in radar?
12 dots

When the SART is 1 ml away from radar, what is the indication in radar?
12 arcs

When the SART is within 1 ml from radar, what is the indication in radar?
12 concentric circles


What is distance covered by SART for activation?
8 NM to a ship
40 NM to a helicopter at the height of 3000 ft – AIRBORNE DETECTION

What is the indication in SART when it is activated?
LED will give a flash each 4 seconds
Buzzer will sound each time the SART is hit by the Radar signals

What are the supporting materials available with SART?
Telescopic pole and 10 meter rope (lanyard) to secure SART

What is AIS SART?

If you see 12 blips in your radar and saw a life raft 8 nm distance
Away from your vessel, what initial action will you take?
Set VHF watch on CH16 and CH06 to contact survival craft
Send DSC Distress Relay alert to all stations/geographical area on 2187.5 KHz

SART TEST

Testing with X band Radar. (3 cm radar. Typical navigational radar.)
Before carrying out SART TEST, check whether any nearby ships are there.
If there are nearby ships, contact them on CH 16 and inform them about the SART TEST.
Now set 12 NM range in the X band radar
Take the SART to the bridge wing and hold the SART at the clear view of the radar scanner (radar aerial). There should not be any obstacles in between the SART and radar scanner
Now in SART,  push and hold the switch to the test position

The person handling radar can see 12 concentric circles in the radar. Adjust the VRM pointer and bring it to the outermost ring of the circles. Display will show 7.2 NM

The person holding the SART, can see a visual light and can hear an audible tone.


How is SART activated?

(In distress situation we use the SART)
Break the seal, pull out the locking pin
Switch automatically goes to ON position (switch is spring loaded)
Now SART is on STANDBY mode.
That means it is ready for transmission

When SART is interrogated by RADAR signal, SART is activated

Maintenance of SART?

Read the Instruction label (how to use and how to test)
Check the battery expiry date and annual service date
Check the lanyard
SART
8NM – SHIP
30NM – Helicopter
