Abstract

Active imaging systems, including laser range-gated short wave infrared (LRG SWIR) systems, are currently being developed to increase the identification range performance of electro-optical targeting systems. This paper reports on the development of an end-to-end simulation of a LRG SWIR imaging system that includes the principle phenomena of beam broadening, beam jitter, scintillation, atmospheric turbulence blur and distortion, laser speckle and camera blur. Although the simulation is restricted to weak turbulence conditions, it is much less computationally expensive than the classical the split-step Fourier-transform algorithm.
