摘　　要：构建了一种基于单片机89C52和DDS芯片AD9831产生水声跳频通信信号的硬件平台。研究了水声跳频图案与混沌跳频序列的特点、跳频通信的数据帧结构,并将跳频编码与FSK调制算法付诸于硬件平台中实现,发射的跳频信号可以控制接收装置的工作状态,外场水库的水声通信试验结果验证了硬件方案的可行性。A hardware platform of UWA FH - SS signal generator with MCU and AD9831 is constructed. The UWA frequency- hopped pattern, characteristic of chaotic frequency hopping sequences and frame structure of FH - SS communication is studied. The FH - SS code and modulation of FSK is realized in the hardware platform. The active state of receiver can be controlled by the FH - SS signal. Performance of our scheme is tested in field experiment The result show that our scheme is feasible in UWA communication.
