摘要
现阶段高速测绘成像雷达回波信号数据量大、传输速率快,完整的实时存储高精度GPS信息的雷达数据是测绘成像的关键,面对此类系统要求满足高精度、数据融合编帧、大容量、高速度、全程准确存储等一系列问题,该文设计一种高速雷达融合数据接口控制存储系统.该系统主控模块以FPGA作为主控芯片,接收10路30 MB/s的LVDS数据和1路GPS串口数据,并进行组合编帧,打包数据通过以太网发送给上位机,最后通过LabView上位机软件将数据存储在硬盘内.最终通过试验验证,可以完整无误地将融合采编数据存储在硬盘内.
Abstract
At present,the high-speed mapping imaging radar echo signal has a large amount of data and fast trans-mission rate.The complete real-time storage of high-precision GPS information radar data is the key to mapping imaging.In the face of such system requirements to meet high precision,data fusion framing,large capacity,high speed,full accurate storage and a series of problems,this study designs a high-speed radar fusion data interface con-trol and storage system.The main control module of the system uses FPGA as the main control chip,receives 10-channel 30 MB/s LVDS data and 1-channel GPS serial port data,and combines and frames them.The packaged data is sent to the host computer through Ethernet,and finally the data is stored in the hard disk through the LabView host computer software.Finally,through the experimental verification,the fusion acquisition data can be stored in the hard disk completely and correctly.
