Scientific paper

Applications of the Cooley-Tukey Fast Fourier Transform (FFT) algorithm to varied computer analysis problems of EO systems are presented. EO systems synthesized by models using the FFT are laser monopulse trackers, COAT, and null trackers such as quadrant detector and spinning reticle seekers. Computation time reductions in excess of 600 times have been demonstrated by the introduction of the FFT.
