Simulated System Of Reliability Of Laser Range Finder

Simulated system of reliability of laser range finder mainly be applied in the distance measuring instrument of fire control equipment of heavy weapon, It is a part from the reliability testing of fire control system.,The measuring system gathering collection of synchronous pulse signal, continuous adjustable precise time-delay device, high accuracy timer and imitation of echo wave into the whole body, it carry out the imitate measuring of function to the pulse laser range finder, but also the distance and energy imitates is independent each other, expel the influence of the environment factor, met the laser range finder of heavy weapons fires control the system on-line examination.The paper put a plan for adopting a kind of new acousto-optic delay device carried out the distance imitate to the sport target, its time continuous adjustable, stable and reliability, it's easy to compatible calculator and control. The device Adopt the constant-ratio electric circuit and time-amplitude conversion, the accuracy of delay time raised biggest.In the energy imitation, making use of the pulse strength controller and narrow pulse pump to carried out the precision control of a pulse strength and the creation time, matching with the high accuracy continuous and adjustable attenuating plate accurately realized the energy magnitude and distribute.
