摘　　要：设计了以EP2C35F484C6为核心的雷达测距系统。系统将雷达传感器输出的模拟信号,经过ADS7863进行模数转换,送入FPGA进行数据处理并显示。其中FPGA使用SPI接口与A/D进行通信并将运算结果存储在内部构建的双端口RAM中。试验仿真及电路试验验证了采用该方案能有效完成24 GHz微波雷达的测距数据的采集。This paper designed the radar ranging system with the EP2C35F484C6 as controlling unit.The analog signal from the radar sensor was converted into digital signal by ADS7863,and then was put into the FPGA for data processing and display.FPGA used the SPI interface to communicate with A/D chip and stored the results into the building up internal two port RAM.Experiment result shows that the 24 GHz microwave radar ranging data can be collected effectively through the method.
