摘要
Abstract
In order to realize unambiguous multi-target range and velocity measurement in FMCW (Frequency Modu-lation Continuous Wave)radar,a trapezoid waveform modulation is proposed and its worst-case matching numbers is de-rived.Then two processing algorithm,TFBM and FGTC,and their matching condition have been innovatively designed. TFBM (Tolerance-Fast Beat frequency Matching)algorithm can quickly find all possible results for each period.FGTC (Fast Ghost Targets Canceling)algorithm can quickly eliminate the ghost targets which are caused by TFBM algorithm. Strictly theoretical derivation and simulation results show that the joint use of TFBM and FTGC algorithm on trapezoid waveform radar can not only measure multi-target range and velocity without ambiguity,but also reduce the computational complexity significantly.关键词
