摘要
简要介绍地音探测器的基本原理，ＳＮ－４数字检波器的频率特性。重点对地音探测器的报警信号处理技术进行了较为详细地论述，给出了消除误报警的实现方法，以及采用鉴别器抑制同频干扰的技术措施。
In this paper, the basic principle of geophone detector and the frequency characteristics of SN-4 digital detector are briefly introduced. The emphasis is placed on the techniques of gophone detector alarm signal treatement and the way to erase false alarm, as well as the technical measures of the inhibition of sharedchannel disturbance with discriminator.
