Analysis of the voice pronunciation mechanism and performance differences of normal voice in the frequency domain, wavelet transform is used to do signal decomposition, and emphasizing characteristics of voice, with these two characteristic parameters we recognize 242 normal voice using gaussian mixture model (GMM) respectively. Put forward wavelet(More)
Aiming at the situation that normal detection means is hard to find the airborne moving target that has a small RCS and rapid moving speed characteristics, the algorithm of moving target detection is presented based on atmospheric wind field disturbing data detected by lidar. First, through receiving atmospheric wind field disturbance information that is(More)
