【摘要】 对于机动目标的成像需要用距离一瞬时多普勒成像方法[4]，文献[4]中给出了目标机动性不强时的成像方法，本文提出了一种自适应的chirplet信号分析方法，在此基础上给出了具有强机动性的目标的ISAR成像算法.最后利用实测数据验证了该方法的有效性．更多还原

【Abstract】 The imaging algorithms available to maneuvering targets can deal only with the targets with first order Doppler variation of scatterers [4]. An adaptive signal decomposition based on Chirplet is given. An imaging algorithm to maneuvering targets with higher order Doppler variation of scatterers based on the decomposition is proposed, which is verified by raw radar data.更多还原
