摘要
被动时差定位系统对高重频信号定位模糊的问题,一直以来是关注的热点。采用时差与测向相结合的方法,依据雷达布站结构,对空域进行合理划分,减少时差配对过程中的虚假配对,在不要求系统具有很高测向精度条件下,有效地改善了对高重频信号定位模糊的问题。
Aiming at the ambiguous location of high pulse repetition frequency(PRF) signal,a new approach combining with radar direction finding is put forward in the paper.According as radar netting and partition to airspace,the approach is able to reduce false time difference of arrival(TDOA) extraction and improve ambiguous location effectively without high precise direction finding accuracy.
