Title: METHOD AND APPARATUS OF USING OPTICAL DISTORTION IN A DIRECTED COUNTERMEASURE SYSTEM TO PROVIDE A VARIABLE FIELD OF VIEW
Abstract:
A single, hard-mounted set of optics is utilized to replace a two field-of-view system for directed countermeasures. It includes within one continuous but distorted field of view the capability to detect, acquire and characterize targets at the edge of the field while precisely tracking with high target fidelity at the field center. With multiple targets, both tracking of a primary target and acquisition of a secondary target can occur simultaneously, greatly improving countermeasure effectiveness.
