Photoelectric measurement device and measurement method of flight projectile spatial burst point three-dimensional coordinates

Abstract

The invention relates to a burst point three-dimensional coordinate measurement device and a burst point three-dimensional coordinate measurement method used in a target range to measure proximity fuse operating distance. The conventional photoelectric detection methods are mainly four-light-curtain junction and charge coupled device (CCD) combination-based measurement methods, and the conventional systems have great measurement errors. The photoelectric measurement device for measuring the projectile spatial burst point three-dimensional coordinates consists of a multi-light-curtain backdrop target, a system power supply, a projectile signal acquisition and processing device and a flame detector; the outputs of the multi-light-curtain backdrop target and the flame detector are connected to the signal acquisition and processing device; the multi-light-curtain backdrop target consists of a first backdrop target and a second backdrop target which are the same, the first backdrop target and the second backdrop target form three detection light curtains respectively, and the intersecting lines of the three detection light curtains and a random horizontal plane are 'N'-shaped in the space; and the first backdrop target, the second backdrop target and the flame detector are sequentially placed along the trajectory direction. The measurement principle is simple; the instruments are simple and convenient to place; and the measurement precision is high.

Description

technical field [0001] The invention belongs to the field of ballistic parameter testing outside the shooting range, and mainly relates to a photoelectric measuring device and method for measuring the three-dimensional coordinates of the explosive point of a flying projectile in space, in particular to a three-dimensional coordinate measuring device and method for measuring the three-dimensional coordinates of the explosive point used in the shooting range to measure the working distance of a proximity fuze. Measurement methods. Background technique [0002] Because the traditional shell fuze is a trigger or mechanical time fuze, the trigger fuze needs to hit the target directly to detonate, and the time fuze needs to pre-set the detonation time, but the length of the detonation time is based on the estimated time required for the shell to fly to the target as the basis. Because the flight altitude and speed of incoming aircraft or other weapons are all random changes, and ...
