A device and method for measuring the moment of hitting a target

Abstract

The invention discloses a measuring device and a measuring method for target-hitting moments. Optical fiber sensors are respectively composed of a single sensing optical fiber, are arranged in a target in a reciprocating mode and cover the target surface area of the target, and the arrangement distance between the optical fiber sensors is smaller than the diameter of an area formed by target hitting of test bullets; optical signals emitted by a light source are transmitted to a photoelectric detector through the optical fiber sensors, converted into electric signals through the photoelectric detector and input into an information collecting and processing module after undergoing signal processing; a time service module obtains the current time information for being used by the information collecting and processing module; when the on-off state signals of the optical fibers are changed to 0 indicating the non-light transmission state from 1 indicating the light transmission state, the time information in the time service module is read and serves as the target-hitting moment. The device and the method can accurately measure the target-hitting moments of the test bullets and can serve as auxiliary analysis means of other range measuring modes, and the extraction efficiency of effective data can be improved. According to the implementation scheme, the method has the advantages that the cost is low, the response speed is high, the measurement accuracy is high, the reliability is high, installing and laying are simple and the anti-jamming capability is high.

Description

technical field [0001] The invention relates to a target time measuring device and a measurement method, belonging to the technical field of target information measurement. Background technique [0002] With the improvement of the strike accuracy of guided weapons, the measurement of target information is also required to be more and more accurate. Accurate measurement of the target moment can not only identify the guidance accuracy of the weapon system, determine the damage effect, and analyze the error factors of the system by synthesizing other target information, but also can be used as an auxiliary measurement method for other measurement methods in the shooting range to improve the accuracy of effective information. extraction efficiency. [0003] At present, the methods of measuring target information mainly include high-speed camera, radar detection, passive acoustic detection, etc., using images, microwave waves, light waves, sound waves, etc. Large, unable to mee...
