BATS AND PORTABLE BATS OPERATION

3-66

 BATS Beacon List setup when tracking 1 Responder with an external trigger.

Scenario: Side Scan Sonar triggers the Responder at the rate as set by the side scan sonar transmitter. Trigger output from the SSS

Transceiver goes into Trigger In 1 of BATS.

 External triggering: Only Target #1 can be externally triggered. All other targets (if enabled) are forced to external trigger

mode.

 Beacon 1 LED’s (Trigger-In (yel), Interrogate (grn), Receive (red)) show status.

 Trigger-In 1 (External trigger) initiates interrogation of Beacon. Trigger-Out 1 signal is transmitted at the time of each interroga-

tion LED flash. Trigger Input rate must be longer than the maximum slant range to the target. E.g., A one-way travel time for a

responder at 1000m is approximately 0.7 seconds (1000 meters / 1500 meter/second = 0.66 seconds).
