The Design of Multi-frequency Radar Data Acquisition System for Adaptive Variable Sampling Rate
At present, the application of Radar ? data acquisition system is single, which doesnt satisfy the wide application demand. A multi-channel adaptive variable sampling rate data acquisition system based on FPGA and I2C bus is introduced. Not only can it be used in the field of multi-frequency radar data acquisition system but also be used to achieve normal data acquisition in industry. By writing the frame data into E2PROM and the design of interface between FPGA and E2PROM, multi-channel data programmable sampling is realized. Also synchronous FIFO integrated in FPGA which can achieve the function of high-speed buffer is presented. Because the sampling rate is controlled by program, so this system which has been used in real test system can be controlled flexibly.
