  1. The intelligent mine will be the most important weapon system to defend arming helicopter hedgehopping in future war. passive acoustic detection technology is the key technology. with the researching of the national defence pre - researching project which is the research of acoustics compound fuse of anti - helicopter intelligent mine, this paper presents acoustic localization algorithm and discusses the affect of wind to the localization, then a method of how to correct the affect of wind has been studied, upon this a dsp software system has been designed

    智能雷彈是防禦超低空飛行的武裝直升機的重要武器系統，而被動聲探測技術是其關鍵技術，本文結合「九?五」國防預研項目「反直升機智能雷彈聲復合引信技術」的研究，對空間目標聲定位演算法和風對被動聲定位的影響及如何對這種影響進行修正進行了深入分析，並在此基礎上設計了dsp軟體系統。
  2. Then analytical measurements of the noise were carried out on both of the turbines by means of modern acoustic apparatus and a conclusion has been found that the noise of the concentrated wind energy turbine is lower than the one of the ordinary wind energy turbine and the root of the trouble to cause noise chiefly originates from the turbine blade. besides, the result of analytical measurement also reveals that the power output both of the wind energy turbines will increase with the increase of the wind speed and unfortunately does the noise too. in order to lower the noise, a measures of noise reduction have been advanced that an active method is to develop a wind energy turbine run at a lower rating of wind speed while the passive method is to adopt a board drilled tiny holes, having established a sound technological basis for the development of a kind of wind energy turbine of low noise and high level in the world
