基于相关系数谱的宽带跳频信号时延估计

Time Delay Estimation of Wide-Band FH Signal Based on Relative Coefficient Spectrum

结合目前跳频信号带宽越来越宽、跳频点越来越多的特点,提出了一种基于相关系数谱的宽带跳频信号时延估计方法,实验表明该方法能够有效实现宽带跳频信号的时延估计,估计精度不受限于采样间隔。并且该算法具有较好的实时性和数据扩展性,易于工程实现。

Currently, the band of FH signal becomes increasingly wider and FH frequencies increase rapidly. Therefore, a time delay estimation algorithm of wide-band FH signal is proposed based on relative coefficient spectrum. According to the experimental result, the time delay estimation is not confined by the sampling distance directly. This method is of good real-time feature and expansibility, which can be realized easily in engineering.
