  1. Due to the short distance among the planes which fly in a group, the conventional low resolution radar can not distinguish them in both distance and azimuth ? if we use the technology of isar to resolve the difference among doppler frequency of the targets and obtain a fine resolution cross - cross image, we may separate them, but a long time of coherent processing is needed <, for the formation targets, it can be approximately divided to rigid body and nonrigid body, so for the formation targets, that can be regarded as rigid which has a relative position and an identical movement, can be approximately considered as a large target, and be compensated by translational phase with the rule of minimum entropy, but for the most those cannot accord with the approximation of rigid, being the doppler - frequency of the aim is linear changed, by the relax method with short data, increases the resolving performance of multiple target to the aim in the frequency domain, since cross - range resolution is based on the accumulative time, so it is greatly improve the resolution to formation targets by the instant cross - range image which produced by radon - wigner transformation

    低分辨isan成像及干涉技術應用研究一因此分辨編隊目標的架數,我們借鑒isar的技術,通過較長時間的相干積累,在多普勒頻域上對目標進行分辨。而對于編隊目標,可分為近似性的多目標和非性的多目標,所以對于可以近似為體的編隊目標相對位置固定,運動方式一致,可以近似看作一個大目標,採用最小墑準則對平動相位的進行補償,但是大多數並不滿足體近似的編隊目標,由於目標在相干積累時間的多普勒頻率近似呈線性變化,通過對較短數據利用relax的時頻分析方,提高了頻率域上目標分辨的性能。由於橫向解析取塊于橫向積累時間,所以利用radnwigner變換得到瞬時的一維橫向距離像大大提高了對編隊目標的分辨,對模擬和實測數據的大量分析結果表明此方的有效性和可行。
