摘　　要：为解决复杂水域同步处理多路水声信号实现水下目标探测的问题,基于PGL12G国产FPGA进行多通道数字检波器设计,可对声传感器接收到的水声信号进行多通道同步滤波处理,并将信号进行全波整流输出实现信号检波作用。该设计使用国产芯片实现主要功能,经过测试验证,结果显示其检波功能正常,功耗较低,能支持长时间水下工作,可用于搭载水下平台实现目标探测。To solve the problem of synchronously processing multiple underwater acoustic signals in complex water areas for underwater target detection,this article designs a multi-channel digital detector based on PGL12G domestic FPGA.It can perform multi-channel synchronous filtering on the underwater acoustic signals received by the acoustic sensor,and output the signal through full wave rectification to achieve signal detection.This design uses domestically produced chips to achieve its main func-tions.After testing and verification,the results show that its detection function is normal,with low power consumption,and can sup-port long-term underwater work.It can be used to carry underwater platforms to achieve target detection.
