Our work concerns multitarget tracking (MTT) for the Strategic Defense Initiative using optical processing. Our three layer system: detection, track initiation, and tracking was detailed in prior reports. Our present work involves a modified optical correlator and a new algorithm for detection, Hough transform extensions for track initiation, and new MTT data and algorithms. We now provide an overview of this work with details given in associated chapters. Chapter (2) provides new algorithm, architecture and simulation results on an AO system to optically achieve the key interpolation and subtraction functions required (1). SDI funds did not allow us to pursue this approach. The new track initiation work included extension of our optical Hough transform optical architecture to new algorithms to handle general curved and object tracks and general 3-D target trajectories using range data. The MTT algorithm and system concept received major attention. Work in this area included the optical laboratory demonstration of a 10-bit analog optical processor using a new architecture and algorithm, attention to the basic algorithmic question of whether a direct or iterative algorithm should be used with an optical processor for nonlinear matrix algorithms such as the extended Kalman filter.
