摘要
总结了多种解决高重频雷达信号时差定位模糊方法的基础上,提出了一种由相关算法推导出的新方法。该方法首先运用直方图计算出高重频信号的不同参差频率和对应的模糊时差,并在此基础上进行时差组合,然后对不同参差频率下的时差进行相关运算最终得出真实的时差。计算机仿真结果表明该方法能够消除时差定位模糊,验证了其可行性和有效性。
A new method based on correlation algorithm is introduced after analyzing many methods which can solve TDOA location ambiguity of HPRF. Firstly, the different frequency and ambiguous TDOA of HPRF with histogram is computed in this method and TDOA combination is applied based on this method. Finally, by correlation computation to TDOA of different frequency, the real TDOA is acquired. By simulation with computer, TDOA location ambiguity is eliminated by this method, it is proved feasible and effective.
