Embodiment 1
[0068] Embodiment 1: see figure 1 and Figure 5 , the method for measuring the flight speed and target coordinates of the double-barreled salvo weapon projectile of the present invention
[0069] When the projectile of the double-barreled salvo weapon flies through the eight-screen test light curtain array, the detection device outputs a corresponding electrical signal, and the eight-way data acquisition device accurately acquires this electrical signal, so as to obtain the time when the projectile passes through the eight light curtains in sequence, and the data It is transmitted to the host computer at the gun position through wireless data transmission equipment. The host computer identifies the flying projectile through the calculation algorithm of speed and target coordinates, stores and displays the flight speed of the projectile and the position coordinates when passing through the target surface. The specific process is as follows:
[0070] one. The geometric struct...
Embodiment 2
[0088] Embodiment 2: implementation method is the same as embodiment 1
[0089] For the measurement of a single projectile, by the surface linear equations in the embodiment 1 step (three) Known, unknown parameters are required , you need to know 6 irrelevant screen surface linear equations, usually four light curtain detection devices , In the generated light curtains, 3 screens are selected respectively, so there are A combination of tests:
[0090]
[0091] 16 test combinations for linear equations full rank, we can get , that is, the flight speed of the projectile and the position coordinates when passing through the target surface can be obtained, and the azimuth and pitch angle of the projectile when flying can also be obtained.
Embodiment 3
[0092] Embodiment 3: implementation method is the same as embodiment 1
[0093] For the measurement of two projectiles, there are 15 cross-screen signals collected by the eight-way data acquisition device as an example:
[0094] 1. Let the velocity of projectile 1 be , reaching the curtain The coordinates are , the velocity of projectile 2 is , reaching the curtain The coordinates are , assuming that projectiles 1 and 2 arrive "only" at the same time , and the time is the "0" time reference point, and the measured projectile 1 reaches the curtain The moments are , Projectile 2 arrives at the curtain The moments are , . Arranging and combining the measured moments, there are a total of combination of moments:
[0095]
[0096]
[0097] For these 128 time combinations, including the real time of each projectile 1 and 2 , .
[0098] 2. Set corresponding decision-making rule algorithm: with 16 kinds of test combinations of embodiment 2 Me...
