Abstract

A functional radar warning receiver backup generator. A functional radar warning receiver backup generator provides threat information in the total absence or partial absence of the radar warning receiver information. Radar warning receiver information such as radar detection data and radar identification data is also generated by other systems such as the Pulsed Radar Jammer and the Continuous Wave Radar Jammer. An on-board computer processes and presents the back-up information to the pilot as if the Radar Warning Receiver was still operational. Voice and video functions of the Radar Warning Receiver are also displayed and presented to the pilot. Partial back-up and full back-up of the Radar Warning Receiver are provided. A temporal data correlation algorithm, a radar emitter ID conversion algorithm, cross sensor correlation algorithm and prioritization algorithm provide the back-up data.
