Target Discrimination/Classification Radar.
Abstract
Adaptive FSK/PSK is a spectrally agile pulse compression rada signaling scheme that learns target-specific information over time & integrates that information into the design of its radar signal processor in real-time. This use of target-specific information into the real-time transmitter signal design process enhances the return from the target, thus improving the performance of the radar system in both additive noise environments (jamming) & ground clutter limited environments (low altitude targets). Since FSK/PSK signaling is a pseudorandom pulse compression scheme with a large time-bandwidth product, it has inherent low probability of intercept characteristics. Additionally, adaptive FSK/PSK signaling is able to earn target-specific information which can be used to identify the target using existing target identification techniques. In this study, the cross-ambiguity function of a general FSK/PSK waveform is derived and analyzed in a probabilistic manner. The results of this probabilistic analysis are used to develop a design methodology what allows the signal to be matched to an arbitrary target. It is shown that both the signal to clutter ratio and signal to noise ratio of a matched FSK/PSK radar are superior to those of a conventional signaling radar that utilizes no target-specific information.
