频率步进雷达多目标ISAR成像方法
Stepped Frequency ISAR Imaging of Multiple Targets
摘要
Abstract
Aiming at the stepped frequency ISAR imaging problems of multiple moving targets in the same antenna beam overlapped over the range ,a new method of stepped frequency ISAR imaging of mul‐tiple targets is proposed ,based on the chirp‐Fourier transform (CFT ) .On the basis of the multi‐target echoes model of stepped frequency radar ,the velocities of each target can be estimated accurately by the CFT .Then the multiple target echo signals can be separated by combining CFT and clean idea ,thus the ISAR imaging is finished .The simulation results also prove the validity of the proposed method .关键词
