Abstract
High fidelity simulation of active tracking systems requires the integration of optical, imaging, control and structural models for the payload with representative target and engagement models. The dependent relationship of actively illuminated target return on beam control system pointing commands particularly motivates an integrated simulation. Simulations of tracking and pointing systems have been developed to allow system algorithm refinement and performance prediction for several acquisition, tracking and pointing experiments. The simulation includes high fidelity, two axis control system models, 2D imaging sensor models, and 3D target geometry and reflectivity models. Key issues addressed include the effects of illuminator jitter coupling into the track error estimates, speckle effects, target reflectivity variations and control system interactions on residual pointing errors. The simulation has been implemented with commercial PC-class hardware and signal processing tools, using databased for specific target geometry and reflectivity maps as a function of engagement timelines. The simulation approach makes it particularly easy for control system and sensor system engineers to integrate discipline-specific models into a system simulation.
