摘　　要：多站时差定位系统对高重频脉冲模式辐射源会出现定位模糊甚至无法定位,严重影响了侦察定位系统的功能实现。论述了无源时差定位原理,指出脉冲重复间隔小于定位基线时间窗是造成时差定位模糊的主要原因,从而提出通过增加定位副站,基于冗余基线方法实现辐射源的定位,得出增加冗余基线方法能实现定位去模糊,有效改善时差定位系统的目标模式的适应性。Multi-station time difference location system will be bLurect or cant rotate L, der high pulse repetition frequency （PRF） pulse mode,which greatly affect the function realization of reconnaissance and location system. This paper discusses the theory of passive time difference location,points out that pulse repetition interval less than location baseline time-window is the main reason to create time difference location fuzzy, thereby brings forward the method based on redundancy baseline to realize emitter location by adding location assistant station, educes that adding re- dundancy baseline can realize location debluring, and effectively improve the adaptability of time difference location system to various target modes.
