Description

technical field [0001] The invention relates to the fields of photoelectric testing and weapon range testing, in particular to a reflective multi-target landing coordinate testing device and method. Background technique [0002] In the field of weapon testing, projectile shooting accuracy and target density are one of the important parameters to evaluate the damage effect of weapons, and the coordinates of projectile landing are important key factors to measure weapon performance. In the multi-target dispersion parameter test of high-frequency burst weapons, it is often encountered that two or more targets are simultaneously targeted. The problem of obtaining coordinate parameters in the case of simultaneous landing of multiple targets is one of the recognized technical problems in the weapon testing industry, and has not been well resolved so far. [0003] At present, the test devices for multi-target landing coordinates mainly include the target plate method, the light cu...

AI Technical Summary

Problems solved by technology

Although the target plate method has high reliability, it consumes a lot of materials, is inconvenient to install, and cannot identify multiple projectiles perforated at the same position. The curtain intersection test method uses the principle of array photoelectric emission and reception to test the target parameters. By obtaining the time value when the target passes through each light curtain, combined with the spatial geometric relationship of multiple light curtains, the position coordinates of the target can be measured.

Due to the complex site layout of the multi-light curtain intersection test equipment, the test accuracy of this test method is affected by the site layout. At the same time, the probability of multiple targets passing through the same light curtain at the same time is relatively high. The calculation of the matching method is complicated; the multi-CCD intersection test system uses multiple CCDs to form the detection target surface, and uses the method of space-time matching to test the target coordinates of multiple targets. It is also impossible to accurately obtain the intersection angle, resulting in low accuracy of the measurement target parameters, which cannot meet the requirements of multi-target target coordinate testing

[0004] To sum up, the existing test technology cannot meet the multi-target target coordinate test requirements of current high-frequency burst weapons, and there is an urgent need for a new type of test device and test method that can meet the multi-target target coordinate test requirements.
