DSP-based design of the lightning location system
Mao Yun-zhi · Microcomputer Information · 2010
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.
