| Abstract: | In this paper, the principle of a micro pulse pressure transduce based on piezoresistive effect is introduced. And the feasibilty for measu ringgunpointnoisebyuseoftheaboved transducer matched multiplechannel data acquisition processing system is probed. The frequency spectrum distribution rule of 12.7mm gunpoint noise is illustrated by processing of a lot of experiment data, which provides basis for our research work in antiaircraft machine gunpoint noise further. |
