Abstract

Abstract: 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）EP3C55F484C8N, 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.

Key words: radar engineering, radar ranging, Rife method, linear frequency modulated continuous wave, field programmable gate array
