Abstract
The laser coherent field imaging system emits multiple beams of laser from earth to space, and the laser scans remote space target by passing through turbulent atmosphere. Turbulent atmosphere is a key factor affecting imaging quality of the coherent field imaging system. Aiming at quantitative simulating of degradation imaging effect caused by atmospheric scintillation, the quantificational simulating experiment platform of atmosphere scintillation is established. Based on the simulating platform, the effect of different intensity turbulence on imaging quality is quantificationally researched. The research draws the conclusion that the greater fluctuation of atmosphere turbulence is, the more serious the degradation of imaging quality is. Thus, in order to improve the imaging quality, the turbulent atmosphere scintillation need to be restrained by signal processing method in the following research. The study provides a achievable quantitative simulating method of turbulent air scintillation for analyzing degradation imaging quality caused by the turbulent atmosphere scintillation.
