Technology Research of Infrasonic Signal Acquisition and Pretreatment for Identification of Nuclear Explosion

Abstract:

The paper designs a kind of nuclear explosion infrasonic signal acquisition equipment and brings forward a pretreatment way. Based on μC/OS and digital circuit of FPGA+ADC, the paper realizes signal acquisition, storage and transmission of infrasound, which is from 0Hz to 20Hz. And according to the characteristics of nuclear infrasonic signal, mean removal, bandpass filter and normalization are used for signal pretreatment. Experiments proved that the signal acquired from acquisition equipment can be used for identification of nuclear explosion.
