Not Available CTI proposes to extend the agile waveform doublet pulse concept to characterize and improve its performance for measuring micro-doppler motion properties of ground and airborne targets from moving platforms at long range. Rather than focus on developing core hardware technologies, the proposed effort serves to take a system-level view of the agile pulse technology to transform the base capability into operational effectiveness. Both airborne and satellite observing platforms are to be considered. Targets include ground surface motion due to underground operations, stationary and moving ground and airborne vehicle targets. Current micro-doppler measurement concepts are limited at long range by a number of noise sources: optical path fluctuations due to advection of turbulence through the lidar beam, line-of-sight jitter, time varying speckle induced by both the relative motion between the target and the observer and by rotational motions of the target, and shot noise. In Phase I detailed modeling and simulation of these error and noise sources will be incorporated into a physics-based model to characterize the performance for different viewing geometries as well as to identify and assess mitigation techniques. The subsequent Phase II effort will extend the physics-based performance model and will demonstrate and validate the mitigation strategies, and improved sensor capability, with appropriately-scaled ground-based field tests.
