In this paper, a new approach to acoustic signals process is described. Firstly, the wavelet transform and the more classical Fourier transform approach to the acoustic signal analyzing and processing is compared. Secondly, acoustic signals of tank, helicopter, truck and human etc. are analyzed. Finally, wavelet technology is used to analyze and extract the(More)
The target detecting and recognizing are the key techniques in the intelligent weapon research. Aimed at the shortages of the higher uncertainty and the worse real-time of battlefield target identification system, the solution, that based on digital signal processor and some necessary devices and circuits are designed to accomplish the high speed target(More)
