摘　　要：介绍了基于Rife法的线性调频连续波(LFMCW)雷达测距算法的原理,给出该算法的实现步骤,并从理论上分析了算法的测距性能。结合可编程门阵列(FPGA)EP3C55F484C8N芯片,进行该算法的编程实现,并将算法嵌入高精度LFMCW雷达中。利用LFMCW雷达进行现场测距实验,实验结果验证了该算法的有效性。A rife-based ranging algorithm for linear frequency modulated continuous wave（LFMCW） radar is proposed. The principle and implementation step of algorithm are presented, and the ranging performance of algorithm is discussed. The implementation method of algorithm is explored in conjunction with the chip of field programmable gate array （FPGA）EP3 C55F484C8N, and the algorithm is embed in LFMCW radar. Finally, the experimental results derived from the field ranging experiment of LFMCW radar prove the validity of the algorithm.
