摘要
在时差无源定位中,高重频信号带来的脉冲配对模糊问题是研究的热点。采用时差与测向结合的方法,根据雷达布站的特点,对空域进行合理划分,减少虚假配对,并利用测向信息研究出现配对模糊的情况,列出方程式求出正确配对脉冲的时差,最后通过仿真验证了本方法的适用性。
The ambiguous location because of high pulse repetition frequency(PRF) signal is a hotspot in DTOA passive location.DTOA and direction finding are combinel and a reasonable partition of airspace is made to reduce false pairing,and equations are arranged to evaluate right pairing of pulse.Finally the simulation is performed to prove the applicability of this method.
