Embodiment Construction

[0043] specific implementation

[0044] A kind of embodiment of the present invention is further elaborated below in conjunction with accompanying drawing:

[0045] The sensor array is arranged as Figure 4 , refer to the system configuration block diagram Figure 5 . Figure 4 Shown is a minimum configuration that satisfies the requirements, two systems each require 3 lightning acoustic-electrical sensor units 10-12, each lightning acoustic-electrical sensor unit contains a VHF broadband omnidirectional antenna (14-16) and lightning Acoustic microphones (18-19), and three lightning acoustic-electric sensor units are respectively placed on the three vertices of a square with a baseline length of 12.5m located on the same horizontal plane. The lightning electric field change measuring instrument 13 is also placed at the center of the array on the above-mentioned horizontal plane as a trigger signal and a reference signal for confirming different lightning discharge process...

Abstract

The invention relates to single-station quasi-three-dimensional lightning positioning device and method. By combining an acoustic signal and an electric signal generated by lightning, the reasonable configuration way of an antenna and a sensor array is designed; by utilizing one acoustoelectric combinative quasi-three-dimensional lightning positioning method, the quasi-three-dimensional positioning result and the space-time evolution process of a lightning discharge channel can be measured and obtained only through a single observation station; the positioning device and the method have the full lightning detection functions of ground lightning and cloud lightning; and simultaneously, the synchronous acoustoelectric comprehensive detection data of the lightning are provided. The positioning device and the method are applicable to weather with higher requirements on the detection precision and the positioning result of the lightning, the detection and the early warning of the lightningfor aviation, spaceflight and military departments, and also can be used as observing and measuring approaches for the physics and the protection research of the lightning.

Description

Technical field [0001] The present invention involves a lightning positioning device and method, and more specifically, it involves a single -station quasi -lighting lightning positioning system and method, which is suitable for single -site lightning detection and early warning. Background technique [0002] Lightning is the instantaneous power process in the atmosphere.Depending on whether the Lightning Channel is grounded, the lightning can be divided into ground and clouds.The high -power electromagnetic environment formed by the backflink backbone and the K -process K process of the cloud flashes pose a significant threat to the safe operation of electrical, electronic equipment and systems.In order to study the damage mechanism of lightning, analyze the physical process of lightning, and effectively warning lightning forecasting, not only the lightning strike point (that is, the "contact point" of the Cavoral Channel and the ground), but also the three -dimensional 3D of th...
