SIMULATION AND TESTING COMPLEX FOR LASER BALLISTIC MEASURING SYSTEM Russian patent published in 2022 - IPC G01P3/36 

FIELD: measuring technology.

SUBSTANCE: invention relates to control and measuring technology and can be used in testing a laser ballistic measuring system. The result is achieved due to the fact that the output of a single-frequency laser is connected to the input of an optical frequency modulator, its optical output is connected to the input of a collimator, the radiation from which is directed at a stationary projectile. The control input of the optical modulator is connected to the output of a controlled frequency divider, the input of which is connected to the output of a high-frequency generator, the control input of the frequency divider is connected to a control and signal processing unit that sets fixed modulation frequencies corresponding to the Doppler frequency shift for the simulated projectile velocity set at a given time interval, while radiation reflected from the projectile is received by a laser ballistic measuring system that calculates the simulated projectile velocity, and the complex determines the errors in measuring the velocity of the projectile, as well as the error in measuring the angular velocity of rotation of the projectile.

EFFECT: accuracy of measuring the initial velocity of the projectile and the angular velocity of rotation of the laser ballistic measuring system.
