The invention belongs to the field of lightning detection, artificial intelligence and deep learning, particularly relates to a lightning electromagnetic wave positioning method, system and equipment based on single-station detection, and aims to solve the problems that an existing single-station lightning positioning method is large in positioning error, low in efficiency and small in range, and a positioning system is prone to interference. The method comprises the following steps: collecting lightning electromagnetic pulse waveform data in real time through lightning electromagnetic pulse detection equipment, and demodulating a received GPS or Beidou time service signal into high-precision time service information; calculating the propagation distance of the lightning electromagnetic pulse through the trained lightning electromagnetic pulse propagation distance prediction model; based on the collected lightning electromagnetic pulse waveform data, calculating the wave orientation of the lightning electromagnetic pulse; and fusing the propagation distance and the wave orientation of the lightning electromagnetic pulse to obtain a positioning result of the lightning electromagnetic pulse. According to the invention, high-precision detection of various types of lightning electromagnetic pulses can be realized, the detection range of a single station exceeds 1000 kilometers, and the positioning precision is superior to 5%.
Description
technical field [0001] The invention belongs to the fields of lightning detection, artificial intelligence and deep learning, and specifically relates to a lightning electromagnetic wave positioning method, system and equipment based on single-station detection. Background technique [0002] Lightning is a high-intensity transient discharge process that frequently occurs in nature. On the one hand, it maintains the electrical balance between the atmospheric ionosphere and the earth; on the other hand, lightning disasters have been listed as "one of the ten most serious natural disasters" by the United Nations Decade Committee for Disaster Risk Reduction. The electromagnetic spectrum of lightning radiation is extremely wide and intense, releasing a large amount of electromagnetic energy in the frequency range below 1Hz to nearly 300MHz. Therefore, electromagnetic pulse detection technology has become the preferred method for lightning detection. [0003] At present, the com...
