ABSTRACT:
A complementary threat sensor data fusion capability for an aircraft survivability equipment system. A set of aircraft survivability sensors provides a threat sensor data fusion control process with status data. The control process controls whether or not a threat ambiguity detector receives radar warning receiver data or a radar emitter ID conversion apparatus receives pulsed radar jammer data or continuous wave radar jammer data. The threat sensor data fusion control process also determines whether missile approach detector data is sent to a countermeasures analyzing apparatus. The threat ambiguity detector provides ambiguity data to a threat ambiguity resolving apparatus. The radar emitter ID conversion apparatus provides converted jammer data to a functional sensor back-up apparatus. The radar emitter ID conversion process receives a common radar emitter ID data base. The threat sensor data fusion process controller also provides fusion process control to the complementary threat data apparatus. Complementary threat data is provided to the pilot through various presentation methods and to the jammers for electronic countermeasures. Also, threat ambiguity resolution data is provided and back-up data is provided. The presentation methods include video and voice and a tactical electronics countermeasures command is automatically initiated. A multi-pass sensor data correlation algorithm and a threat prioritization algorithm share information with the threat ambiguity resolving algorithm, complementary threat data algorithm, functional sensor back-up apparatus, and electronic countermeasures apparatus. The direction of jamming is determined by data correlation between the radar warning receiver and the CW Jammer.
