摘要
针对多通道功能复用脉冲或脉冲多普勒(PD)引信测距误差较大,严重制约引信超低空性能的问题,提出基于独立测距通道的超低空无线电引信.该超低空无线电引信由目标探测通道和独立测距通道组成,其中目标探测通道采用PD体制,独立测距通道采用线性调频连续波(LFMCW)体制.仿真分析结果表明,基于独立测距通道的超低空无线电引信安全距离仅需 0.7m,在目标探测通道距离波门调整过程中引信目标探测区得到最大程度的保留,同时具备 3m高度飞行目标的近距探测能力.
Abstract
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.
