Embodiment Construction

[0060] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0061] First of all, the working principle of the blasting point location system of the present embodiment is as follows: due to the long distance of the blasting point of the shell (4 kilometers for the rocket launcher and 6.8 kilometers for the antiaircraft gun), the energy of the sound wave that can be transmitted back is small and difficult to collect. To ensure that the acoustic signal with sufficient energy can be collected, this system collects and analyzes the subsonic signal of the shell explosion. The front end consists of a four-point equidistant array receiver unit composed of four subsonic signal collectors based on moving coil subwoofer signals to collect the subsonic signal of the shell explosion, and then undergo a primary amplification, filtering, secondary amplification, and then a High-speed AD acquisition is converted into d...

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...
