Abstract
This chapter mainly discusses the non-ideal motion error compensation issue in GMTIm with real SAR data. Pointing at the problem that existing GMTIm algorithms have poor performances in the real SAR data processing, the impact of Doppler centroid is analyzed. The signal model of a moving target with non-ideal motion error is established, and the platform velocity error and cross-track velocity error of the moving target are analyzed. Moreover, an error estimation and compensation algorithm is presented, and a whole practical SAR data processing scheme with the algorithms in the frontal chapters is proposed. Finally, simulations and real data are utilized to prove the effectiveness of these algorithms.
