Semi-active laser-guided energy transmission and simulation technology

Analysis on calibration and control of diffuse laser signal in guidance simulation

“…The instability of laser energy emitted by a laser refers to the random of laser source pulse energy and the change of laser source output energy trend under a given working condition. The instability of laser energy mainly affects the accuracy of the simulation system in two aspects: when calibrating the laser signal energy transmission parameters of the system, the energy instability of the laser source is one of the main error sources in the calibration process, and its influence needs to be eliminated by technical means; When using the laser as the signal source for simulation testing, the energy instability of the laser source simulates the characteristics of the field mounting equipment, and the difference between the random fluctuation of the laser pulse energy and the light emission characteristics of the simulated object can be regarded as the inherent error of the system [7]- [8] .…”
