An ECHO II tracking experiment was attempted using the coherent focusing radar (COFFER) system developed under Contract AF30(602)-2750. The objective was to investigate acquisition time, coherency of focus and tracking capability of the equipment when used with a satellite target. The COFFER equipment was previously optimized for aircraft targets and depended on externally supplied look angles from another radar for target acquisition. For use with ECHO II, the system was modified somewhat and an optical tracking subsystem was added for aid in acquisition. However this method of acquisition was effective only during visual passes of the satellite in good weather which did not prevail during the time available. Only limited results were obtained for this reason. (Author)
