Although Frequency Modulated Continuous Wave(FMCW) laser fuze has the advantages of high ranging precision and strong electromagnetic anti-interference capability etc., laser detectors are susceptible to the clouds, smoke, rain and snow, which will influence the target recognition. An FMCW laser and radio compound detecting technology is presented, which can effectively help the laser detecting system to avoid from those interference. Based on the analysis of the working principles of FMCW laser detecting technique and FMCW radio detecting technology, a laser and radio compound detecting scheme is put forward, and the feasibility of the system is verified.
