Abstract
In 1979, CAI began the development of the KS-146A 1676-mm (66-inch) focal length, f/5.6 frame camera system designed exclusively for long range oblique photographic (LOROP) missions. The goal was to produce a stabilized system tailored for use with relatively slow, but high-definition films such as EK 3412 and 3414 while also providing growth potential to an electro-optical (E-0) real-time sensor. A detailed design description of the system was presented during SPIE's 1981 symposium. Since then, six systems have been fabricated, evaluated and flight tested over a wide range of airborne conditions. All systems are now operational and the results obtained have confirmed that all objectives have been achieved. Airborne resolution of 8.5 prod (70 Ip/mm) has consistently been demonstrated at slant ranges exceeding 30 nmi. Modular construction and the flexibility inherent in the KS-I 46A design makes the conversion to an E-0 sensor straightforward, and the effort to expand the capabilities of the system have begun. Details of the camera development and a review of flight test results are presented. The modifications to convert the system to near real time are also discussed.
