Abstract

The Comprehensive Nuclear-Test-Ban Treaty adopted four technical means to monitor nuclear tests, which are the seismic, radionuclide, hydroacoustic and infrasound monitoring techniques. The infrasound monitoring technology is an effective tool for monitoring the atmosphere, ground or water nuclear explosions. The FK method is an array signal processing method used to estimate the slowness and azimuth of infrasound signals, but the resolution of this method is not high. This method is also susceptible to the influence of noise and the pseudo-peak is obvious. So this article introduces a High-resolution method-the Capon method, this method has been widely used in the signal processing of radar, communication and sonar. Based on the features and characteristics of the infrasound signals, the performance of the algorithm is analyzed and compared with the FK method, the results show that this method is superior to the FK method.
