摘　　要：空时自适应处理(STAP)是机载雷达信号处理中的一项关键技术,近年来机载双基地雷达STAP的研究成为热点。机载双基地雷达表现出复杂的杂波特性,即严重的杂波距离相关性,导致传统STAP方法杂波抑制性能严重下降。为此,本文首先对现有解决机载双基地雷达STAP面临的杂波距离相关性问题的典型方法的机理和特点进行了分析,然后对各种解决杂波距离相关性的方法进行了综合比较评价,最后得出结论:基于谱配准的杂波距离相关性补偿方法是解决存在距离模糊时机载双基地雷达距离相关性问题最有潜力的方法。Space time adaptive processing （STAP） has become a critical technique to be applied for airborne phased array radar. Researchers have given STAP considerable attention in the past several years. Complicated clutter characteristic, i. e. , clutter range-dependence, exists for airborne bistatic radar seriously, and the conventional statistical STAP methods cannot be applied to airborne bistatic radar. In this paper, the principles and characteristics of typical methods for solving clutter range-dependence of airborne bistatic radar are analyzed, then a general comparison and evaluation are given. Finally, the conclusion that Registration-Based Compensation （RBC） method has the potential to solve the problem of clutter range-dependence under range ambiguity conditions is obtained.
