基于时频分析的微动弹道目标ISAR成像方法
Ballistic Target ISAR Imaging Based on Time-Frequency Analysis
摘要
Abstract
When ballistic target is moving with micro-motion,the Doppler frequency of its scattering points will be modulated by micro-motion which will have negative effect on imaging.In this article,a new meth-od called time selection imaging based on abor transformation formula is put forward,which will focus im-age effectively.The proposed method seerches the Ddoppler fraguency in time quantum of syraight line ap-proximation in time-frequency domain for the target And the effectiveness of this method is verifies by simulation.关键词
