Design and Implementation of Small Target Detection Sonar Control Module Based on FPGA

给出了一种基于FPGA小目标探测声纳的发射与控制设计方案,介绍了该方案中利用Verilog HDL语言和FPGA IP Core相结合的方式实现发射与接收控制模块功能来满足系统的需求。根据探测声纳系统需求,通过上位机选择发射模式,下发指令控制发射波形,来产生探测声纳发射信号,之后通过对A/D芯片的控制,并对采集数据进行打包编码,使用UDP协议通过千兆网电路上传到干端上位机中进行实时处理。

A design scheme of launch and control based on FPGA small target detection sonar is presented.The combination of Verilog HDL language and FPGA IP Core is used to realize the function of transmitting and receiving control module to meet the system requirements.According to the requirements of the detection sonar system,the host computer selects the transmission mode,and issues the command to control the transmission waveform to generate the detection sonar transmission signal,and then controls the A/D chip,and encodes and encodes the collected data,using the UDP protocol.It is uploaded to the dry host computer through Gigabit network circuit for real-time processing.
