多基地雷达多基地雷达multistaticradar由分置于不同基地的发射机和接收机统一组成的雷达系统。它可有多种组成形式，各基地上的发射机和接收机可以是一部或多部，且数量不必相等。多基地雷达适用于对远距离目标精确定位。它同单基地雷达一样，可对目标进行检测、定位、跟踪和测速，但它用目标对各基地的距离、角度和距离差等数据表示目标的坐标。多基地雷达也可用脉冲信号或连续波调频信号测量距离。为测量多普勒频移，可把发射基地的发射信号传送到接收基地作为参考信号。但在接收基地对目标进行角度测量时，这个直接信号有可能对目标回波信号造成干扰，须使直接信号与回波信号隔离。在这里，多普勒频率用于鉴别目标是否为静止，但不能确定目标的径向运动速度。与单基地雷达相比，多基地雷达的数据处理系统要复杂得多，且存在虚假目标现象，需利用其他辅助信息和相应的数据处理方法来消除或减少。多基地雷达除在军事上对入侵目标精确定位、导弹精确制导外，还可用作空间飞行器的精确弹道测量系统等。
