Abstract

Scattering centers extracted from radar returns are features that can be used for automatic target recognition (ATR). Most scattering center extraction algorithms fall into one of two large classes: FFT-based and model-based techniques. In this paper, we consider one FFT- based and two model-based techniques: (1) FFT with peak extraction, (2) the Burg autoregressive method, and (3) the TLS-Prony method. We present experiments that compare the algorithms for three test scenarios. We compare the algorithms in terms of scattering center accuracy and computational cost.
