Fourier signal processing is an enabling technology that applies to three of the identified technology areas in BAA HQ0006-02-AC-BAA. These include (1) Radar Systems Signal Processing, (2) Lasers & Electro-optics; Optical Signal Processing, and (3) Mathematics and Computer Processing. Drawing on work done in medical signal processing, we seek to expand the Fourier processing technology developed for cardiology to military applications. During the course of developing the medical optical signal processor, it was noted that the adaptive spatial filter that had been developed for cardiology and retinal imaging was applicable to the exploitation of aerial photographs & images. This was determined to be due to the similarity in the Fourier power spectra of the medical and reconnaissance image
