Radar Target Discrimination and Identification Using Extinction-Pulses and Single-Mode Extraction Pulses

摘要

The goal of this research program is to develop an efficient new radar targetdiscrimination and identification scheme based on the natural frequencies of the target. It consists of synthesizing aspect-independent discriminant signals including Extinction-pulse (E-pulses) and Single-mode extraction pulses (S-pulses) which, when convolved numerically with 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 signals will be significantly different from the expected zero or single-mode responses, thus, the differing targets can be discriminated. Major achievements on various topics under this research program are described in this report.
