摘　　要：论文根据主动定向浮标工作原理,简要分析了主动定向浮标所需信号形式及技术指标,利用VHDL语言在CPLD上进行片上开发,实现主动定向浮标信号发生器的设计。实现的信号包括单频控制信号以及CW脉冲信号和LFM信号,同时对遥控指令进行曼彻斯特解码来实现对发射信号脉冲宽度的控制,为了进一步使系统硬件电路稳定工作,在进行发射脉冲信号设计的过程中,实现了保护电路的设计。Based on the principle of active directional buoys, the active directional buoys form of the desired signal andtechnical indicators are analyzed briefly, the VHDL language in the on-chip CPLD development, achieve active directional buoyssignal generator. Implemented signal comprises a single-frequency control signals, is used to CW pulse signal and LFMsignal, while the remote commander is manchester decoded to achieve the transmit signal pulse width control, in order to furthermake the system hardware stability, in transmission pulse signal design process, the protection circuit design is realized.
