Problems solved by technology

At present, commonly used measurement equipment can be divided into contact measurement and non-contact measurement. The main test equipment includes paper target board measurement method, multi-light curtain intersection measurement method, double CCD intersection measurement method, acoustic target, etc., all of which can only test In the case of a single target at the same time, when multiple targets are simultaneously targeted, a large number of false targets will be obtained, resulting in the fact that the existing test methods cannot be used for the position distribution test of multiple targets simultaneously, which is the weapon parameter test. One of the technical problems recognized by the industry

[0003] In view of the situation where two projectiles hit the target at the same time, some researchers proposed to use seven detection light curtain arrays to measure the projectile landing coordinates of the double-barreled weapon. The device and algorithm are complicated and difficult to realize in actual engineering.

Some researchers proposed to use the measurement principle based on six light curtains, subdivide each light curtain into multiple small light curtains, and realize the measurement of coordinates when two projectiles hit the target at the same time. This method has complex composition of light curtains. When two projectiles hit the target at the same time and the target position is in the same light curtain area, the system also cannot distinguish, which eventually leads to the inability to measure

[0004] Existing patents also propose some coordinate measurement methods for simultaneous landing of multiple targets, but there are certain problems. For example, the patent "Measurement Method and Device for the Flight Velocity and Target Coordinates of Double-barreled Salvo Weapon Projectiles" proposes to use eight detection light The method of curtain array is used to measure the target coordinates of the projectile of the double-barreled weapon. The system device and algorithm are complicated, and it is difficult to realize in actual engineering.

For example, the patent "Multi-tube salvo weapon projectile velocity and target coordinate measurement device and measurement method" proposes to adopt the measurement principle based on six light curtains, and divide each light curtain into multiple small light curtains, so as to realize the simultaneous landing of multiple projectiles. For the measurement of coordinates in the case of a target, the composition of the light curtain in this method is complex, and engineering implementation is difficult. When two projectiles hit the target at the same time and the target position is in the same light curtain interval, the system is also unable to distinguish, which eventually leads to the inability to measure

The patent "Coordinate Measuring Device and Measuring Method for Simultaneous Targeting of 2-3 Projectiles" proposes a measuring device and method based on a high-speed color line array CCD camera combined with a line laser light source. The high-speed line array used in this scheme The color camera is expensive and depends on imports, so the price of the system is relatively expensive, and this method cannot be used for the situation where 4 or more projectiles hit the target at the same time

For example, the patent "a laser multi-target vertical target measurement device and measurement method" proposes to use multiple sets of line lasers and photoelectric detection arrays to form a detection target surface. If there are N targets at the same time, N+1 sets of line lasers and photoelectric detection arrays are required. Photodetector array, as the number of targets that need to be tested at the same time and the thickness of the target surface increase, it is impossible to test small targets, such as the test of fragment groups.
