摘要
结合雷电电磁辐射和雷声能谱的特点,提出以声传感器组成五元十字阵接收雷声实现雷电定向,以声电延时计算雷电距离,以计算雷声能量从而表征雷电能量给出雷电强度的雷电定位方法。并给出了基于DSP的系统设计思路。根据现有资料估计,系统有效探测距离可达20～30km,有望达到±5°的俯仰角估计精度和±2°的方位角估计精度,距离估计精度小于340m。
Based on the characteristics of thunderbolt which are electromagnetism radicalization and thunder energy spectrum, give an thunderbolt location method which uses five member structured cross array to get elevation and azimuth of thunderbolt, by computing time delay between sound of thunder and light to get the thunderbolt distance , and by computing energy of thunder as intensity of the thunderbolt.And give design way based on DSP.Estimate by information in existence, this system detect distance is 20～30km, and be hopefully reach ±5° elevation precision and ±2° azimuth precision.
