Embodiment 1
[0053] Example one see Figure 1-Figure 4 As shown, the lightning positioning method with multiple sound sensors is characterized by:
[0054] Step 1. The unknown lightning coordinate is point P, and a sound sensor is arranged at each of the four spatial observation points O, A, B, and C. The sound sensor is a microphone or a recorder, and the sampling speed is ≥30 microseconds. The sound sensor 1 is a microphone or Audio recorder, sampling speed ≥30 microseconds, light sensor 2 is a wide-angle camera, four sound sensors are connected to the four signal input channels of a four-channel data acquisition card, and the output of the four-channel data acquisition card is connected to the signal input of the data processing system Interface connection
[0055] The coordinates of the four observation points in space are O(x o , Y o ,z o ), A(x a , Y a ,z a ), B(x b , Y b ,z b ), C(x c , Y c ,z c ), then the distances of the three spatial observation points A, B, and C to point O are fix...

Abstract
The invention relates to a thunder and lightning locator with sound sensors and a locating method thereof. The thunder and lightning locator comprises four sound sensors, a four-passage data acquisition card and a data processing system, wherein the four sound sensors are distributed on four observing points; when thunder and lightning occur, the sound sensors positioned on the four space observing points respectively record the thunder reaching time of the observing points; four groups of time data are converted from A/D (analog to digital) by the four-passage data acquisition card and then transmitted to the data processing system; the data processing system solves the difference of the thunder reaching time of three space observing points through logical operation and computes the difference of the distances of the three space observing points according to the propagation speed of sound in the air; and a coordinate of a thunder and lightning generation position is determined according to an equation set and a principle that a point can be determined by intersecting three hyperboloids in space. The invention ensures high measurement precision, also simplifies a locating measurement method, reduces the hardware requirements and the equipment cost, realizes the accurate automatic locating of the thunder and lightning and can be widely used in the field of meteorological sounding.
Description
Technical field [0001] The invention relates to the technical field of weather detection, in particular to a lightning positioning method. Background technique [0002] At present, the lightning positioning methods generally recognized internationally can be roughly divided into five types. The first is to improve the gated magnetic pulse orientation method, such as the widely used ground flash directional instrument (DF), which can identify the LF (low frequency) frequency band radiated electromagnetic field waveforms of typical ground lightning, and determine the peak value and orientation of the discharge waveform . Multi-station DF network can determine the location of lightning. The second is the long baseline TOA (Time of Arrival) technology that works in the LF band, such as the Lightning Location and Tracking System (LPATS). The third is the interferometer method that works in the VHF (very high frequency) frequency band. Its characteristic is that it can detect cloud ...
