Complex spatial filters for automatic target recognition and feature aided tracking

摘要

Complex sapatial filters derived from maximizing a unique objective function are applied to Automatic Target Recognition (ATR) in SYnthetic Aperture Radar (SAR) both to grayscale images and directly to phase history (sensor) data. For a limited class of MSTAR targets, a high degree of discrimination is shown in both cases. Applications to tracing are discussed and some areas for future investigation are indicated.
