  • 摘要: 包絡(luò)對齊是寬帶回波預(yù)處理中重要的一部分,然而對于空間錐體這類只有較少散射中心且目標(biāo)存在微動的情況,現(xiàn)有的包絡(luò)對齊方法并不能得到較好的對齊結(jié)果。對于一些利用寬帶回波進(jìn)行微動目標(biāo)參數(shù)估計的算法,包絡(luò)對齊是其算法的關(guān)鍵一步。該文提出一種基于極化散射特性進(jìn)行包絡(luò)對齊的算法,算法首先利用極化譜估計與幅相聯(lián)合估計(P-CAPES)超分辨方法估計寬帶極化回波中的散射中心的數(shù)目、位置和極化散射矩陣,然后計算前后時刻回波散射中心的極化相似性參數(shù),最后利用得到相似性參數(shù)進(jìn)行包絡(luò)對齊?;陔姶庞嬎銛?shù)據(jù)的實(shí)驗(yàn)結(jié)果驗(yàn)證了算法的有效性。
