    低分辨isan成像及干涉技術用研究一因此直接無法分辨編隊目標的架數,我們借鑒isar的技術,通過較時間的相干積累,在多普勒頻域上對目標進行分辨。而對于編隊目標,可分為近似剛性的多目標和非剛性的多目標,所以對于可以近似為剛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剛體近似的編隊目標,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的時頻分析方法,提高了頻率域上目標分辨的性能。由於橫向解析度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法的有性和可行。
