摘要
A method of radar target discrimination and identification is presented. This method 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 is significantly different from the exptected zero or single-mode responses; thus, the differing targets are discriminated. Theoretical synthesis of discriminant signals from known target natural frequencies and experimental synthesis of them for a complex target from its measured pulse response are presented. The scheme was tested with measured responses of various targets in the laboratory.
