Abstract

The invention provides an acoustics and electromagnetism-based thunder positioning system and method. The system comprises a sound source positioning device, a synchronous data acqusition card and a data processing device, wherein the sound source positioning device comprises at least three sound pickups and one antenna; the plane of the three sound pickups and the horizontal plane form an acute angle of being smaller than 90 degrees; the synchronous data acqusition card is in signal connection with the three sound pickups respectively; the data processing device is in signal connection with the synchronous data acqusition card and the antenna and is used for acquiring position of thunder on a map according to different thunder sound information and time information received by the three sound pickups and acquired by the synchronous data acqusition card. The system and the method have the beneficial effects that the system has a simple structure, and the influence of factors such as landform on observation due to longer thunder distance, the influence of noise amplitude in monitoring of a surrounding environment at different time periods and error influence caused by individual difference of directivity and amplitude response nonlinearity of an electret microphone and the like are effectively reduced.

Description

technical field [0001] The present invention relates to the technical field of thunder positioning, in particular to a thunder positioning system and method based on acoustics and electromagnetics. Background technique [0002] At present, most developed countries and regions have built nationwide or regional lightning monitoring networks, but my country is relatively lagging behind in this field, and the research and development of lightning monitoring and early warning is still in its infancy, lacking a nationwide unified monitoring network. Therefore, we must improve the level of lightning monitoring technology in a short period of time, so as to comprehensively develop military meteorology, aerospace, power systems, forest fire prevention, and salt field mining. [0003] Monitoring various physical coefficients and occurrence locations of lightning phenomena is the basic task of lightning monitoring and positioning technology. This technology is also an important basis f...
