The Laser Detecting Set (LDS) AN/AVR-2 consists of five components: four Sensor Units mounted on the forward pylon fairing assembly (one facing forward and one facing aft on the left and right side of the aircraft) and one Interface Unit Comparator mounted inside the battery compartment. The AN/AVR-39(V)1 and AN/APR-39A(V)1 Family Radar Signal Detecting Sets (RSDS) control panel, display indicator, and processing are used with the AVR-2 LDS to provide testing capability, and visual and audio interface to the operator. This interface between the AN/AVR-2 LDS and AN/APR-39(V) series RSDS allows them to function as an integrated radar and laser warning system. The AN/AVR-2 LDS detects, identifies, and characterizes laser signals 360 degrees in four 100 degree fields-of-view and + or- 45 degrees in elevation around the aircraft. The AN/AVR-2 LDS detects laser radiation illuminating the aircraft, processes the laser threat data into laser threat messages, and transmits the messages to the AN/APR-39(V) series RSDS for visual display indicating the direction of the threat. Audio signals will also be available through the helicopters intercommunications system. The AVR-2 LDS provides threat data so that countermeasures can be taken, improving the aircrafts survivability.
