Simulation of laser ranging system for LEO non-cooperative targets based on Monte Carlo method

摘要

In this paper, the signal model, the noise model and the error theory of the laser ranging system which aims at non-corporative target and capable of performing in daylight condition, is established. Monte Carlo method is applied to simulate the photon incident detection result of the laser ranging system. The simulation result also shows the trajectory of space target which has radial maneuver as well as disturbance. Finally, two parameters, the accumulation pulse number and laser repletion ratio are optimized according to the simulation.
