Abstract
A system and method for three-axis stabilization of focal plane data. The system and method include performing a two-dimensional vertical shear transformation and a two-dimensional horizontal shear transformation. The system and method further incorporate a SIMD computer architecture and an array of addressable processing elements that process the field-of-view for a target image received by a focal plane array of detector elements. Each processing element includes a calculation device that calculates the row and column address of virtual pixels for a virtual field-of-view. The system and method further include a plurality of memory modules configured to store data in a plurality of addressable storage locations by column and row, and each memory module is identified with a different processing element. A dedicated memory routing network for the processing elements and memory modules permits the exchange of information between processing elements and memory modules associated with each processing element.
