How To Operate In Emergency

1. Dismantle SAR-9 SART from the installation bracket.

2. Remove the security clip so that the switch indicates ON.

3. The SART indicates that it has been triggered by lighting an

indicator blue LED continuously (it flashes in standby mode) and by

sounding an integral buzzer. If no radar pulses are detected for a

period exceeding 15 seconds, the SART reverts to “standby” mode.

4. Use the fixing rod, the tightening stripe or the fixing ring in the life

rafts of the mother ship so that SAR-9 can be separated for 1 m

or above the sea surface.

1. Summary.

The model SAR-9 SART(Search And Rescue Radar Transponder) has been designed

to meet the standards of GMDSS as a small-sized & light radar transponder for search

& rescue and it provides the accurate information on the position of any life boats, life

rafts and the mother ship in disaster.

When it catches a 9GHz radar signal, it informs people in distress of approaching

rescue with its blue lamps and at the same time, transmits reply to SAR craft. The

reply signal appears in the radar display with the data originating at the location of the

SART to facilitate the process of search and rescue.

According to the IMO regulations, any ships more than 300 gross tonnage but less

than 500 gross tonnage should be equipped at least with 1(one) SARTs for search

and rescue. Ships of 500 gross tounage and more should be equipped at least with 2

SART.

For the installation on the inside of survival rafts, life boats and wall sides of mother

ships, the equipment includes a rod mount, a fixing ring, a bracket mount etc.

3. SART principle of operation

Actuating a SART enables a survival craft to show up on a search vessel’s radar

display as an easily recognised series of dots.

Radar (radio detection and ranging) is a device carried by most ships which is used to

determine the presence and location of an object by measuring the time for the echo

of a radio wave to return from it, and the direction from which it returns.

A typical ship’s radar will transmit a stream of high power pulses on a fixed frequency

anywhere between 9.2GHz and 9.5GHz. It will collect the echoes received on the

same frequency using a display known as a Plan Position Indicator (PPI), which

shows the ship itself at the center of the screen, with the echoes dotted around it.

Echoes further from the center of the screen are thus further from the ship and the

relative or true bearing of each echo can be easily seen.

The SART operates by receiving a pulse from the search radar and sending back a

series of pulses in response, which the radar will then display as if they were normal

echoes. The first return pulse, if it sent back immediately, will appear in the same

place on the PPI as a normal echo would have done. Subsequent pulses, being

slightly delayed, appear to the radar like echoes from objects furthernaway.

A series of dots is therefore shown, leading away from the position of the SART.

This distinctive pattern is much easier to spot than a single echo such as from a radar

reflector. Moreover, the fact that the SART is actually a transmitter means that the

return pulses can be as strong as echoes received from much larger objects.

A complication arises from the need for the SART to respond to radars which may be

operating at any frequency within the 9GHz band. The method chosen for the SART is

to use a wideband receiver (which will pick up any radar pulses in the band), in

conjuction with a swept frequency transmitter. Each radar pulses received by the

SART results in a transmission consisting of 12 forward and return sweeps through

the range 9.2GHz to 9.5GHz. The radar will only respond to returns close to its own

8 SAR-9

frequency of operation (ie. within its receive bandwidth), so a “pulse” is produced at

the radar input each time the SART sweep passes though the correct frequency.

A slow sweep would give the radar a stronger echo to deal with as the sweep would

be inside the operating bandwidth for a longer period. The delay for the sweep to

reach the operating frequency may however lead to an unacceptable range error, as

delayed echoes appear to be coming from more distant objects.

To minimise this problem, the SART uses a “sawtooth” response, sweeping quickly,

then slowly for each of its twelve forward and return sweeps. At long range, only the

slow sweeps, giving the strongest returns, are picked up. At close range, where errors

are more important, the fast sweeps are also detected. As the first sweep is a fast one,

then the range error is minimised and should be less than 150 metres.

The timescale over which all this occurs is very short. Each “fast” sweep takes about

0.4µs, each “slow” sweep about 7.5µs. The complete series of twelve forward and

return sweeps is therefore complete within 100µs. Displayed on the PPI, the spacing

between each pair of dots will be 0.6 nautical miles.

On a long range setting, a typical radar will be triggering the SART every millisecond –

but only during the period that the rotating radar scanner is pointing in the correct

direction. Most modern radars use sophisticated noise rejection techniques, which

prevent the display of echoes which are not synchronized with the radar’s own

transmissions, so one radar will not normally be confused by a SART’s response to a

neigbouring radar.

5. Installation

The preferred mounting location is inside the vessel, which the device can be

protected. Generally it is installed in the port side and starboard of vessel or the place

where it can readily be accessed near an emergency exit in the event it is needed.

As figure 3, fix the mounting bracket to a bulkhead in a convenient location. The

recommended fixing is by M5 marine grade stainless steel bolts (4 pcs) and nuts(4

pcs). The length is dependent upon application.

Mount the SAR-9, dome uppermost and battery down, onto the bracket by locating the

lugs on the SAR-9 pole mount into the slots in the bracket. Push down the SAR-9 into

place.

6. Operation

In case of emergency, lift SAR-9 from bulkhead bracket.

To switch on:

1. Lift the security clip away from the body of the SART.

2. The SART automatically rotate the switch ring clockwise to the ON position marked.

3.The SART indicates that it has been triggered by lighting an indicator blue LED

continuously (it flashes in standby mode) and by sounding an integral buzzer. If no

radar pulses are detected for a period exceeding 15 seconds, the SART reverts to

“standby” mode.

To extend the mounting pole:

1. Grasp EVA (rubber) cover at bottom of pole, and twist the pole to release it in the

pole mount. Pull the pole down and twist to lock in place in the pole mount.

2. Remove EVA (rubber) cover from bottom of pole; allow pole sections to drop. Lock

sections together by twisting each section.

To deploy in a survival craft (liferaft):

1. Extend the SART supporting pole as detailed above.

2. Tether the SART to a suitable point using the lanyard which unwinds from its

base.

3. Inset the SART through the port in the canopy.

4. Position the bottom of the support pole in the antenna pocket. Secure the pole

to the canopy support.

Some survival craft have the SART already packed as part of the inventory. In general,

these models of SART are not fitted with the support pole. The SART should be

swithed ON then suspended by its top loop from the highest point of the survival craft.

If the lanyard becomes unwound, it may be rewound by rotating the spool in the base

of the SART in the direction of the arrow.

7. Self Test Facility

Regular testing of the SAR-9 SART is advised. The duration of the test should be

limited to as short a time as possible as the SART response may be received by other

vessels which are within range.

The are no operation differences between TEST and ON modes; the rotary switch

must be held in the TEST position, on release it returns to the OFF position.

1. Insure compliance with all applicable Health and Safety instructions when working

in proximity to a radar transmitter.

2. Lacate the SART within the line of sight of an operating approved marine Radar.

3. Rotate the switch ring anticlockwise (ie to the right) to the TEST position, and hodl it

in this position.

a) if the SART responds to the radar, the blue light in the base of the SART

will be continuously lit and the buzzer will sound every 2 seconds.

b) if the SART does not respond to the radar, the blue light will flash every 2

seconds and the buzzer will not sound.

The SART must respond to the radar to pass the test.

4. Switch off the SART by releasing the switch ring; check that it returns fully to the

OFF position.

5. During the annual survey, perform the self test and verify the SART performance by

observing the response on the radar.
