摘　　要：线性调频连续波雷达（LFMCWR）是1种通过对连续波进行频率调制来获得距离与速度信息的雷达体制。随着信号处理设备的工作频率越来越高，传统的低速定点DSP已不能满足设计需求。TMS320C6678作为新一代多核DSP芯片，具有丰富的高速接口，介绍1种通过FPGA的逻辑编程去控制TMS320C6678的EMIFl6总线，实现线性调频连续波雷达的信号传输和处理的方法，为多核DSP的开发与使用提供1种借鉴。LFMCW is a kind of radar system that measure the distance and velocity of target with the continuous wave frequency modulation. In modern times, with the frequency of the signal processing equipment becoming higher, the traditional low speed fixed-point DSP could not reach the design requirements. However, TMS320C6678 is a new generation of multi-core DSP chip that has multi high speed interface. In this paper, a kind of FPGA hardware program controlled the EMIF16 module of TMS320C6678 to realize the LFMCW signal transmission and processing is introduced, which can provide a reference for the development and application of multi-core DSP.
