摘要
对某敏感型电点火具采用低通滤波器设计技术,对其进行原理分析与设计计算,同时对电点火具进行防射频性能试验。结果表明在电场辐射频率为10kHz^18GHz,场强为20~60V/m的条件下,该电点火具可以满足武器系统防射频要求,低通滤波器能有效降低和消除各种频段的射频干扰,保证敏感型电点火具的防射频能力,且电点火具性能不受影响。
Low pass filter was used for anti-RF in the sensitive electric igniter. The design theory was analyzed, and its calculation was made, at the same time the anti-RF test of electric igniter has been done. Result indicated that on the condition of electric field with 10kHz-18GHz radiation frequency, 20-60V/m field strength, the electric igniter can meet with the anti-RF demands of weapon system. The low pass filter can effectively decrease and eliminate the radio-frequency interference of some frequency band, ensure the anti-RF ability of sensitive electric igniter, and the performance of electric igniter isn＇t change.
