Shell explosion point positioning system and positioning method

Abstract

The invention discloses a shell explosion point positioning system and positioning method. The positioning system comprises a receiver unit, an environment parameter collecting unit, a central processing unit and a wireless communication unit. The receiver unit comprises four receivers distributed in a four-point isometric array mode, the receivers and the environment parameter collecting unit are connected to the central processing unit, and the central processing unit is connected to an upper computer unit through the wireless communication unit. The four-point isometric array receiver unit is adopted to collect subsonic signals of shell explosion, the subsonic signals are subjected to preprocessing to be converted into digital signals, and time identification is endowed to each fragment of digital sonic signals. Signal waveform converting and interference and noise removing are finished, the time difference existing when shell explosion sound waves are transmitted to the receivers is extracted, the coordinates of the shell explosion point are worked out according to a mathematical model, and the specific position of shell explosion is positioned. By means of the shell explosion point positioning system and the positioning method, safety of human operation can be improved, the danger coefficient can be reduced, and the operation effect can be improved.

Description

technical field [0001] The invention relates to the technical field of acoustic positioning, in particular to a shell burst point positioning system and positioning method. Background technique [0002] Antiaircraft artillery systems and rocket systems are weather modification devices widely used throughout the country. Their main purpose is to launch a large number of high-explosive shells to bombard hail clouds when hail weather threatens, eliminating or weakening hail disasters; Choose an opportunity to launch silver iodide to increase precipitation. [0003] In actual operation, due to the influence of the reliability of operating ammunition, the threat of dud bombs appears from time to time, and the unstable orbit of the rocket also affects the evaluation of the operation effect. The threat of dud bombs is mainly reflected in three aspects: first, the unexploded warheads are not broken, and their whereabouts pose a danger to ground personnel and facilities; second, une...

AI Technical Summary

Problems solved by technology

The instability of the orbit of the rocket not only affects the operation effect, but also poses a great threat to the explosion near the ground. It is necessary to track and monitor the quality of the rocket

[0004] At present, weather modification operations generally lack positioning or fire control devices for bombardment points. In response to this demand, this system is designed to be used in blasting point positioning for weather modification operations and a tracking and positioning system for rocket operation monitoring.
