摘要
在车载雷达接收机系统中,通常需要将接收到的数据进行处理与存储。基于国产FPGA+DSP架构的电路设计,接收机电路模块集成了AD采集和RSSD盘存储两个单元,实现了信号处理与数据存储于一体的功能,提高了接收机的集成度。该接收机已应用于某车载雷达系统中,实现了16位分辨率的100 MHz以下中频信号的AD采集与数据处理,能够存储高达2 TB容量的数据,极大提高了车载雷达接收机系统的数据处理与存储一体化性能,整个电路模块的功耗仅为8 W,器件全部实现国产,主要芯片均由笔者所在单位自主研发。
In the vehicle-mounted radar receiver system,it is usually necessary to process and store the received data.Based on the circuit design of domestic FPGA+DSP architecture,the receiver circuit module integrates AD acquisition and RSSD disk storage,so that the function of integrating signal processing and data storage is realized,and the integration degree of the receiver is improved.The receiver has been used in a vehicle-borne radar system,which can realize AD acquisition and data processing of IF signal below 100 MHz with 16-bit resolution,and can store data up to 2 TB capacity,which greatly improves the integrated performance of data processing and storage of the vehicle radar receiver system.The power consumption of the whole circuit module is only 8 W,and all the devices are made in China,and all the main chips are independently developed by the author’s unit.
