| 摘 要： | 时差定位对于高重频雷达会产生时差模糊的现象。而脉冲配对产生的大量模糊时差,不仅降低了处理速度,还会干扰对其它信号的时差提取和信号分选处理。本文提出了一种新方法,很好地解决了信号处理和正确定位的问题。

| Abstract: | The TDOA(time difference of arrival) ambiguity may occur in TDOA location with high PRF(pulse repetition frequency). The large numbers of ambiguous TDOAs produced by pulse pairing, not only reduce the speed of processing, but also interfere the extraction of TDOA produced by other signals and pulse deinterleaving. A new method is presented to solve the problems of signal processing and location effectively. |
