Abstract

This paper examines moving targets detection using single channel Synthetic aperture radar (SAR) in spaceborne platform. Building on previous work moving targets can be retrieved from multi-look images via magnitude subtraction or phase interferometry. A more effective method is proposed which mainly consists of signal subspace processing-based data equilibrium and change detection in multi-look covariance matrix. Also different baseline is checked and weak targets may be found. Test results show that precise calibration of multi-look images are essential and short baseline is preferred when the interesting targets are weak. Therefore, the proposed method leads to improved detection performance and provides ways of GMTI in single channel SAR.
