Ultralow Altitude Radio Fuze Based on Independent Ranging Channel
Aiming at the problem that the ranging error of multi-channel functional multiplexing pulse or pulse doppler(PD)fuze is so large,which seriously restricts the performance of the fuze in ultralow altitude,an ul-tralow altitude radio fuse based on independent ranging channel was proposed.The ultralow altitude radio fuze was composed of a target detection channel in which the PD system was adopted and an independent ranging channel in which the linear frequency modulated continuous wave(LFMCW)system was adopted.The simula-tion results showed that the safe distance of the ultralow altitude radio fuze based on independent ranging chan-nel was only 0.7 m,and the detection area of the fuze was preserved to the greatest extent during the adjustment of the range gate of the target detection channel,and it also had the short-range detection ability of the flight tar-get at a height of 3 m.
