| 摘 要： | 根据跳频码速率与直扩码速率之间的关系,DS/FH信号可以分为快跳DS/FH信号、等速DS/FH信号和慢跳DS/FH信号。针对慢跳DS/FH_BPSK信号的DS特性对FH特性检测的影响,提出了一种慢跳DS/FH_BPSK信号的FH特性检测方法——平方倍频时域滤波互功率谱密度法。计算机仿真结果表明该方法具有一定的效果。

| Abstract: | According to the variety of relationships between the FH chip rate and the DS chip rate, hybrid DS/FH signal with coherent frequency hopping can be classified into three catego- ries. A method for detecting the frequency-hopping character of slow-hop hybrid DS/FH BPSK signal is provided based on improved Time-Domain Filtered Cross Spectrum Density （TDF- CSD）. The proposed method is proved effectively by the simulation results. |
