Moving Target Parameter Estimation of Spaceborne SAR-GMTI Based on the Analysis of Acceleration
Aiming at the influence of fast moving target with acceleration in imaging and parameter estimation, a novel method for moving target detection and parameter estimation with three-channel is proposed. After the moving target echo is analyzed, the general two-order keystone transform is applied to eliminate range curve for clutter suppression result. Time-frequency analysis is employed to construct phase compensation function and correct the residual range walk. Finally, azimuth Fourier transform is performed to get the image. Moving target parameters can be obtained by the interferometric processing technology. Simulation results show the validity of the method.
