Abstract

The invention provides a shoot range multimode fusion placement measurement system comprising an optical fiber sensor grid hit point measurement subsystem, a heterodyne coherent detection phi-OTDR placement measurement subsystem and a burst point acoustic positioning measurement subsystem. The system is used for high-precision positioning of missile burst points and placement of a shoot range and assessment of the hit point damage effect. Omnibearing measurement of target hit, air burst and ground placement can be realized by a multiregional optical fiber sensor grid, multi-array acoustic sensors and surface/subsurface sensing optical fibers. All-weather and omnibearing measurement and assessment of actual combats under various working conditions can be met, a real-time shoot indication function of the shoot range can be realized, continuous multi-target placement measurement can be realized through fusion of multiple measurement modes, and high-precision placement positioning and assessment of the hit point damage effect can be realized so that the shoot range multimode fusion placement measurement system has advantages of high reliability, low construction cost and high precision.

Description

technical field [0001] The invention relates to a multi-mode fusion impact point measurement system in the end area of ​​the shooting range. The system is based on OTDR technology, acoustic positioning technology and optical fiber sensing technology, and adopts a multi-mode fusion measurement method, which is applied to the impact point measurement technology in the end area of ​​the shooting range. field. Background technique [0002] With the improvement of the accuracy of the weapon system, higher requirements are put forward for the reliability and accuracy of the shooting range drop point measurement. In order to complete the measurement task of the shooting range, data reliability and all-weather measurement are two important considerations. [0003] At present, optical methods such as infrared automatic tracking, infrared miss-target measurement, target infrared radiation characteristic measurement and thermal image live recording have been widely used in missile aer...
