Embodiment Construction

[0019] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0020] figure 1 It shows that an embodiment of the present invention provides a lightning location method, including:

[0021] S11. Obtain lightning pulse signals received by at least four lightning detection sub-stations within a preset collection time period, and location information of the lightning detection sub-stations.

[0022] In this step, it should be noted that, in the embodiment of the present invention, due to the determination of the location information and occurrence time of the target lightning, the determination of the four unknown values ​​requires the synchronization of at least four sub-stations based on the calculation formula Data is used as a supp...

Abstract

The embodiment of the present invention provides a lightning location method and device. The method comprises the steps of: obtaining lightning pulse signals received by at least four lightning detection sub stations in a preset collection time quantum and position information of the lightning detection sub stations; according to the lightning pulse signals, determining one pulse peak corresponding to each lightning detection sub station in the same target lightning discharge event as a target pulse peak group, and obtaining generation time corresponding to each pulse peak of the target pulsepeak group; employing a TDOA (Time Difference of Arrival) to determine initial position information of the target lightning according to the position information of the lightning detection sub stations and the generation time corresponding to each pulse peak of the target pulse peak group; and performing grid processing for a preset range of a near space of the initial position information according to the initial position information, and employing a time reversal method twice to determine the position information of the target lightning to achieve improvement of location accuracy of the lightning.

Description

technical field [0001] The invention relates to the technical field of meteorological research, in particular to a method and device for locating lightning. Background technique [0002] Lightning is a disastrous natural phenomenon, which has caused great harm to human production and life. It can cause casualties, cause fires in oil depots and forests, cause failure or damage to power supply and communication information systems, and pose a major threat to aviation, aerospace and some important and sensitive high-tech equipment. Lightning can be roughly divided into two types: ground lightning and cloud lightning. Among them, ground lightning accounts for about one-third of the total lightning, while cloud lightning, including intra-cloud discharge process, inter-cloud discharge process and cloud-air discharge process, accounts for about one-third of the total lightning. Two-thirds of the total number of lightning bolts. At present, the lightning location network used by d...
