摘要

ISAR成像中散射体通过分辨单元(MTRC)进行偏移是常见的问题,陆光月和郑宝(1998)提出了一种简单的方法来补偿ISAR成像中的MTRC。本文分析了该算法的特点,并在回波分析的基础上给出了距离多普勒算法(RDA)、MTRC补偿算法(MTRCCA)和极坐标形成算法(PFA)的相互关系。结果表明,MTRCCA对模型的依赖性较弱,适用于ISAR成像。

Analysis of MTRC compensation algorithm in ISAR
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.
