声音识别技术在气象炮射作业监测中的研究与应用

he work of changing weather through manpower needs put gunnery operation into practice, and it has strong timeliness. So there is necessary to build a suit of gunnery operation monitor system for meteorology with high automation, and timeliness. The measuring the number of cannonball in this system is through the method of the gun sound recognition to come true. In the traditional basis of speech recognition, this design is aimed at recognizing the gun sound, and use Matlab to analyze variety of recognition algorithms with a certain improvement. It detecting the gun sound signal has more robust, and it is designed a simple sound recognition algorithm fitting for gun sound detecting. In part of implementing algorithm into hardware, there is introducing a realization scheme based on FPGA, and describing the hardware design briefly.
