Matched FSK/PSK radar

In this paper, a novel radar signaling scheme designated as matched FSK/PSK signaling is introduced. An overall radar system which implements matched FSK/PSK signaling along with the appropriate processing scheme is given. Radars of this type are shown to be capable of generating FSK/PSK signals optimally matched to any arbitrary target response. The radar signals consist of bursts of pulses, whose frequencies are chosen by a random selection process with a probability density function based on the radar target´s spectral content, and whose phases are a pseudo-random spreading sequence. The capability of the radar to match its illumination to a target could prove to be vital in tracking low observable targets. Additionally, the spectral agility of the matched FSK/PSK system allows for spectrally adaptive signaling. Adaptive signaling could not only aid target tracking, but also provide information about the target that could be used for target identification purposes
