Abstract

Potential approaches for the simulation of the effect of atmospheric turbulence and target speckle on active imaging systems are considered. In particular, computationally tractable methods of applying representative degradation to simulated burst illumination laser imagery are investigated. This is motivated by the fact that the traditional phase screens approach for the simulation of the effect of a turbulent atmosphere on light propagation can require large computing resources to implement parameter sets approaching those appropriate for realistic scenarios. This is undesirable for scene simulation applications where there are typically already considerable demands on computing resources. This is the context in which the various options considered are assessed.
