Abstract

Simulation Extension: The overall objective of the Simulation Extensions project is to identify and quantify those generic mission, scenario and sensor parameters (as well as their interactions) which drive the performance of space-based staring IR surveillance systems. The approach taken to achieve their overall objective has proceeded along two main avenues; Simulation Enhancements, and Simulation Applications. Efforts in the Simulation Enhancements areas are directed toward generalized those models in the Draper Integrated Simulations which are too limited in scope or perhaps restricted to one particular system. In support of the Simulation Enhancements effort, work was performed (or is in progress) on models for the platform, sensor (including focal plane and signal processor), and scene. Utilizing the tools developed as a result of the Simulation Enhancements work, the Simulation Applications effort studies issues related to generic surveillance system performance drivers. Results are reported from a study which examines the effects of spectral band selection and scene local time of day on line-of-sight jitter-induced clutter leakage through the signal processor of a generic surveillance system. Halo Optics: CSDL prepared a deconvolution test to validate Itek's deconvolution algorithm for correcting a deformed HALO optical system. The algorithm uses the wavefront errors measured by a wavefront sensor to determine the actuator signals. This report describes a limited blind test and concludes that the algorithm successfully determine the actuator displacements from the wavefront errors provided in this test.
