| 摘 要： | 在DSFFH混合扩频通信系统中，快速捕获是一个非常关键的技术。通过采用快速扫描和等待式相结合的方法用来实现跳频信号的快速捕获，利用神经网络技术实现直扩信号的快速捕获，通过这2种方式，就可实现DSFFH混合扩频的快速捕获。

| Abstract: | In hybrid Direct Sequence/Frequency Hopping Spread Spectrum (DS/FH SS) system, the fast acquisition is a key technique. A combined fast scanning and waiting method for FH acquisition is introduced, and a neural network for DS acquisition is presented also. Using these two methods, the fast acquisition of the hybrid DS/FH SS system can be realized. |
