Aimed at the limitations of the conventional linear frequency modulation continuous wave（LFMC） radar during moving multi-target pairs.Combining with a variable cycle as the transmission signal waveform LFMCW

using a new way of cohesive centric processing of multi-target pairing to achieve goals exactly matching and distance speed to the coupling

which effectively improves processing algorithms in real time.Reasonably set the width of the threshold pool centers can achieve the exact target matching and distance speed to coupling.The test results show that matching error is less than 5 %.
