Design of Digital Detector Based on PGL12G Processor
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.
