Paper 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.
