Analysis of MTRC compensation algorithm in ISAR

Abstract

Migration through resolution cell (MTRC) of a scatterer occurs often in ISAR imaging, and a simple method is proposed in Guangyue Lu and Zheng Bao (1998) to compensate MTRC in ISAR imaging. In this paper, the characteristic of the algorithm is analyzed, and the relationship of three algorithms, range Doppler algorithm (RDA), MTRC compensation algorithm (MTRCCA) and polar formation algorithm (PFA), is given based on the analysis of the echo. The results show that MTRCCA is weakly dependent on the model and is suitable in ISAR imaging.
