Abstract

Laser range gating imaging is currently the main means of underwater optical remote detection. The imaging signal-to-noise ratio is the core indicator of the distance gating system, which directly determines the limit detection distance of the system. In this paper, the imaging signal-to-noise ratio of the distance gated imaging system is theoretically analyzed. Based on the theory of laser transport in water, the time and space broadening effect of laser transmission, backscattering and imaging optical modulation transfer function(MTF) decline are all considered. Finally, the final form of the signal-to-noise ratio(SNR) and the simulation results are given.
