A flight test has demonstrated single-ship geolocation capability for Raytheon’s ALR-69A(V) all-digital radar warning receiver.

The company says this function enhances aircrew survivability and provides "sensors forward" situational awareness at lower costs than competing systems through simple software modifications.

The ALR-69A(V) radar warning receiver. Geo-location capabilities offer aircrews more options, allowing pilots to decide whether to maneuver to avoid or prosecute a threat. Before this geo-location capability, aircrews only had an approximation of the direction of the threat signals.

The ALR-69A(V) now provides aircrews precise information on ground-based threat locations and precision-direction finding for airborne threats.

By using four independent Digital Quadrant Receivers, each covering one quadrant of the aircraft, the ALR-69A(V) provides signal selectivity and management of possible interference emanating from wingmen, coalition partners, and commercial aircraft. The result is improved detection range and accurate identification of friend versus foe.

A 16-channel broadband receiver can be reconfigured to support future applications and, as converter technology continues to improve, users can boost response time and dynamic range by replacing a digital circuit card. Extra, pre-wired card slots enable interfaces to electronic countermeasure or radar systems.
