摘要

摘要: 运动目标的多普勒参数对常规SAR成像具有一定的影响，该文根据目标的运动参数与多普勒参数的关系，组合并改进相关成像技术，提出了一套SAR运动舰船成像流程。该方法不仅能对单通道信号中的运动目标进行良好的聚焦成像，而且能将其成像在正确的位置。仿真实验和实测数据的成像结果验证了该方法的有效性和正确性。

Abstract: The Doppler parameters of moving targets affect the conventional Synthetic Aperture Radar (SAR) imaging. In this study, the relation between the motion and Doppler parameters is established. With improved popular technology, a set of moving ship SAR imaging processes is proposed to obtain a focused and rightlocated image. Simulations and experimental data are used to verify the method.
