Having extracted the power spectrum density matrix changing according to time(PSDMCAT) of the cross-correlation function of FH signals,the method can estimate such parameters as hop-timing,hop-rate,dwell-time and frequency-set by analyzing the hops which are generated from PSDMCAT.
提出一种跳频信号参数估计的方法,该方法首先求出跳频信号的互相关函数及其随时间改变的功率谱密度矩阵,并从该矩阵中生成跳频信号的时频hop图,最后通过对hop的分析得出跳频信号的跳时、跳速、驻留时间和频率集等参数。
