Paper Abstract

A physics-based target detection theory is developed for spotlight-mode operation of a synthetic aperture radar (SAR). The target return and clutter return models are constructed from electromagnetic scattering theory. A polar-format Fourier-transform processor for spotlight-mode SAR images with adjustable processing durations, and a Neyman-Pearson optimum whitening-filter processor for single-component targets are considered. Detection performance for these spotlight-mode SAR processors are compared with those for corresponding stripmap- mode SAR processors. Target detection theory for multi- component targets is also developed. For two conditions -- unknown component phases, and unknown component phases with uncertain component positions -- we develop likelihood-based detectors and numerically evaluate the associated receiver operating characteristics.
