Paper Abstract

We have recently been examining the performance of coherent laser radar systems for theater missile defense missions from an airborne platform. The application requires long range performance from a light weight, small volume system using existing technology. Specialized signal processing is required to efficiently extract the maximum information from the available laser output power. In this paper we consider methods to improve system performance by combining several laser radar pulses, showing that, in the presence of target fading, incoherent pulse averaging is superior. We describe a straightforward calculation method for incoherent pulse averaging. Steady and unsteady pointing errors degrade the performance of a coherent laser radar system in an airborne application. We present a calculation method and predictions of the performance penalties associated with jitter and boresight error for fading targets.
