Synthetic aperture radar (SAR) is an invaluable tool for detection of ground moving targets when combined with processing techniques of ground moving target indication (GMTI). This work investigates a simulation methodology for studying impact of site-specific ground clutter on SAR-GMTI performance. A terrain model is proposed and is based on digital terrain elevation data (DTED) and national land-use land-cover data (NLCD) as provided by the US Geological Survey. The proposed physical optics simulation method capitalizes on high-fidelity digital target models in combination with the proposed terrain model. SAR phase history is generated for a moving commercial target in situ of site specific clutter. The normalized radar cross-section (NRCS) clutter is modeled according to empirical random processes. As SAR imagery and GMTI detection performance depend on clutter, the well-known displaced phase center antenna (DPCA) algorithm is applied to test the performance of the SAR-GMTI algorithm. A Sobel gradient edge-detection technique is used to discern target energy from ground clutter in the SAR image as a means to estimate signal-to-noise-plus-interference ratio (SINR). The proposed model is shown to be suitable for studying the effects of measured clutter on SAR-GMTI performance.
