Abstract:

Adaptive FSKPSK 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 FSKPSK signaling is a pseudorandom pulse compression scheme with a large time-bandwidth product, it has inherent low probability of intercept characteristics. Additionally, adaptive FSKPSK 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 FSKPSK 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 FSKPSK radar are superior to those of a conventional signaling radar that utilizes no target-specific information.
