中文摘要：
目前应用于雷达的数据采集系统应用环境单一,不能满足宽领域的应用需求。一种基于FPGA和I^2C总线的多路自适应采样系统既可以用于多频连续波雷达数据采集系统中,又适用于常规工业领域中的数据采集。将采样帧数据存入E^2PROM并通过FPGA与E^2PROM接口设计实现了多路数据采样率可编程方法,并提出了一种基于FPGA片上集成的高速FIFO实现采集数据的高速缓存。由于采样率由程序控制,因此该方案具有较强的灵活性,已成功应用于实际系统。
英文摘要：
At present, the application of radar data acquisition system is single, which isn＇ satisfied for the wide application demand. A multi-channel self-adapting data acquisition system was introduced based on FPGA and I2C bus. It can be used in the field of multi-frequency radar data acquisition system, and be used to make normal data acquisition in industry. By writing the frame data into E^2 PROM and the design of interface between FPGA and E^2 PROM, multi-channel data programmable sampling was realized. The synchronous FIFO integrated in FPGA which can achieve the function of high-speed buffer was presented. Because the sampling rate is controlled by program, so this system which has been used in real system can be controlled flexibly.
