Wavefront curvature compensation in PFA for spotlight bistatic SAR with arbitrary platforms paths

Wavefront curvature compensation in PFA for spotlight bistatic SAR with arbitrary platforms paths

Polar format algorithm (PFA) as is an efficient algorithm can be well applied to spotlight bistatic synthetic aperture radar (SAR). However, a planar wavefront assumption which leads to image distortion is made. In this study, a new method to compensate for the wavefront curvature of PFA image is pr...
