Abstract

To solve the problem of motion compensation for accurate shadow inverse synthetic aperture radar (SISAR) imaging, an SISAR motion compensation algorithm based on dual-frequency is proposed. By conjugate multiplication of two echo signals with different carrier frequencies and different sampling rates, the influence of the scattering phase can be compensated and Doppler phase shift can be obtained by resolving recursive equations. Further, the Doppler variation rate at the baseline-crossing time is used as the initial value to solve the recursive equations. The simulation results show that this algorithm can give a more accurate SISAR contour image, the resolution of which has been greatly improved compared to that obtained by traditional SISAR motion compensation methods.
