Research of artillery´s sound recognition technology

The relevant departments take some operation activities of weather modification, such as launching shell or rocket to air, for developing and utilizing the water resources in the air. In order to regulate the management, it is necessary to build a suit of gunnery operation monitor system for meteorology with high automation and timeliness, in which the automatic detection technology of lunching shells´ number is essential. This paper mainly introduces how to realize the method of detecting lunching shells´ number, based on the sound recognition technology. We put forward improvement algorithms with analyzing and comparing the traditional speech recognition algorithms, and make it be more robust. The algorithms are used in detecting the artillery´s sound, and it is achieved the aim through Matlab simulation. In part of implementing algorithms into hardware, a realization scheme based on FPGA is introduced, and described the hardware design simply.
