探测

Aimed at rapidity and low power consumption required by intelligent mines,based on correlation theory and pattern recognition technology,a new method is given,in which helicopter noise signal of time domain is analyzed directly,that is to estimate fundamental frequency by calculating self-correlation function,then recognize target thinking of the fundamental frequency as characteristic quantity.

预警识别是被动声探测的关键技术之一，其作用是探测环境噪声信号作为预警信号，当直升机或其它目标出现时，传声器检测到的声能首先被转化为一定幅度的电压信号，电路通过判断信号的大小和其它特征来确定是否出现直升机目标。

The plateau environment of hyperpiesia and hypoxia in Tibet makes the occurrence and development of fires different with inland in characteristics and laws,which determines a different prevention and detection for fires between the Tibetan Plateau and the inland. Especially,the fuel gas characteristics for plateau burning will have a great impact on the prevention and detection for fires at high altitude.
