Warning and Surveillance Sensors

This article shows you Warning and surveillance sensors from Diehl BGT.

PIMAWS

PIMAWS (Passive Infrared Missile Approach Warning System) is a warning system for aircraft operating with passive IR sensors, which detect attacking enemy missiles and initiate countermeasures. Owing to its detector, optics and high scan rate, this very small unit can monitor a very large angular range within a very short time. Two of these units each mounted to the upper and lower sides of the aircraft cover the entire airspace around the object to be protected. The IR sensors enable PIMAWS to detect approaching missiles even if their rocket motor has burned out. PIMAWS is planned to be used, for example, in the Airbus A400M for whose missile approach warners Diehl BGT Defence and MBDA France have submitted a joint proposal.

GBIRST/SIRST

The GBIRST (Ground Based InfraRed Search and Track) infrared surveillance units and its ship-borne equivalent, SIRST ("S" stands for "ship"), are used for automatic surveillance of the airspace around an object to be protected and for detection of air targets such as aircraft, missiles, drones, UAVs, and helicopters. GBIRST is also suited for surveillance of airports or harbor facilities as it can also acquire mobile targets on the ground or afloat. SIRST provides performance similar to GBIRST, is however optimized for use aboard naval and commercial ships and can also identify dangerous objects on the water.
Major characteristics of both units are comprehensive 360° coverage in azimuth and elevation up to 55°, with a data refresh rate of 5Hz with extremely low false-alarm rate and reaction times of under 2 sec.
