Abstract

A technique for radar target discrimination using multiple-frequency scattering amplitude data is investigated. Based on the concept of natural resonance frequencies, the technique is aspect-angle independent. This is achieved through simple signal processing, thus providing nearly real-time operation. The radar cross sections (RCS) of spheroids are calculated numerically to simulate the received radar returns for discriminating different spheroids and wires in the resonance frequency region. The simulation also takes into account the effect of noise which appears in practical measurement
