Abstract

In this paper we extend the capabilities of the Wave Process in three major areas. This is a continuation of work that was reported earlier. The Wave Process can now adapt its behavior to detect a point target moving with an arbitrary velocity while still rejecting stationary background and clutter. It can also adapt to different target velocities simultaneously occurring at different locations on the focal plane. This is achieved through neuromorphic methods, without recourse to clocks, programmability, or other aspects of the digital processing paradigm. We also present a single planar circuit that performs the functions of the positive, negative, and wave-sum planes, with a more efficient analog VLSI implementation for on- focal plane integration. Finally, we develop a more through understanding of the Wave Process performance through numerical simulations of the ideal modeling equations and SPICE simulations of the ideal hardware representations for stationary sources and moving targets.
