摘　　要：针对曳光榴弹的曳光火焰对无线电引信工作的影响,进行了靶场遥测和地面定量测试,发现曳光会使弹体天线引信射频输出端有数百毫伏噪声,绝大部分能量集中在100 Hz以下。采用脱离弹体天线的微波引信可防止曳光的影响;在弹体天线引信中增加高通滤波,可有效克服曳光噪声对引信工作的影响。Aim at the affection of tracer flame to tracer shell, telemetering and quantitative tests were made. The results indicate that there is noise of hundreds millivolts at the fuze RF output end of projectile body-type antenna. Most of the energy is lower than 100 Hz. A microwave fuze which replaces projectile body-type antenna by a microstrip antenna can prevent the effect of tracer. Adding high-pass filtering in the fuze with projectile body- type antenna can effectively reduce the affection of tracer noise on fuze working.
