Design of Radar/GPS Data Fusion Storage System Based on FPGA
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.
