Itek Corporation has performed a three-part study that addresses the use of hybrid opticalelectronic processing techniques for high range resolution imaging radar systems. The first part of the study was an investigation of the processing requirements of the HR-cubed system. Parametric evaluations were performed that related processor capabilities such as number of parallel processing channels to the basic system operating parameters such as cross-range resolution, target density, target range, and target velocity. The second part of this study included a survey of hybrid processing systems that have already been assembled. This survey covered illustrative examples of the different types of hybrid processors, including power spectrum analyzers, Fourier transform filtering systems and synthetic aperture radar processors. The third part of this study developed a strawman hybrid processor for HR-cubed image generation. In keeping with hybrid design philosophy, the system included optical subsystems for pulse compression, mass storage, Fourier transformation, and image correlation.
