The purpose of this research is to develop a new scheme of radar discrimination and identification. The new scheme is based on the natural frequencies of the target. It consists of synthesizing aspect-independent discriminant signals, called Extinction-pulses E-pulses and single-mode extraction signals which, when convolved numerically with the late-time transient response of an expected target, lead to zero or single-mode responses. When the synthesized, discriminant signals for an expected target are convolved with the radar return from a different target, the resulting signal will be significantly different from the expected zero or single-mode responses, thus, the differing targets can be discriminated. The theory on E-pulses and single-mode extraction signals is outlined based on the time-domain and the frequency-domain analysis. Experimental results on complex targets are given. Some new methods for extracting the natural frequencies of a complex target from its measured pulse response are presented.
