Optical fiber underwater sound collision part and target-missing amount measuring system

Abstract

The invention discloses an optical fiber underwater sound collision part and target-missing amount measuring system. The system comprises an optical fiber grid measuring subsystem, an optical fiber hydrophone measuring subsystem, a wireless receiving display control terminal and a ship-borne wireless communication device. When a test bullet hits a target ship, the optical fiber grid measuring subsystem collects optical fiber on-off information of the collision area; and when the test bullet does not hit the target ship and falls into water, the optical fiber hydrophone measuring subsystem collects sound signals generated when the test bullet falls into water. The wireless receiving display control terminal is used for receiving and analyzing collected data, and therefore the collision position or the target-missing amount information of the test bullet is obtained. According to the optical fiber underwater sound collision part and target-missing amount measuring system, the collision damage information can be answered in real time, meanwhile, the measurement on the target-missing amount during target missing of the test bullet is achieved, cost is low, and reliability and measuring precision are high.

Description

technical field [0001] The present invention relates to the measurement system of the impact position and the amount of miss, in particular to the measurement system of the impact position and the amount of miss based on the optical fiber grid sensing technology and the hydrophone detection technology, which is applied to the impact position measurement and test when the target ship on the sea is hit. The field of measuring the amount of miss when the missile misses the target. Background technique [0002] The strike accuracy of a guided weapon is directly related to the killing effect of the weapon. The measurement of the impact position when the target is hit and the measurement of the miss amount when the test projectile misses the target play a key role in identifying and evaluating the performance of the offensive weapon. The performance of guided weapons is generally reflected in the encounter stage of the target and projectile, while the killing effect of the weapon ...

Problems solved by technology

Among them, the explosion point positioning method based on seismic wave detection disclosed in patent CN103389014A is only suitable for land shooting ranges, and cannot be used for sea shooting ranges

Patent CN102829957A discloses the method of measuring the amount of misses using infrared tracking technology, which belongs to the type of radar detection. The detection range of this method is limited and the cost is expensive.

Other measurement methods also have certain limitations. The ballistic analysis measurement method requires formula calculation of the trajectory, and the measurement accuracy is difficult to guarantee. The high-speed camera method is easily affected by the weather, and the image processing method has slow processing speed, poor real-time performance, and insufficient accuracy. shortcoming
