RENDEZVOUS AND STATION-KEEPING OPTICAL RADAR (RASKOR).

The Rendezvous and Station-Keeping Optical Radar RASKOR system is an optical radar system utilizing GaAs injection lasers and solid-state optical detectors. The application of RASKOR is for aircraft rendezvous and station-keeping. The system is designed for use with cooperating targets, under conditions for which passive visual techniques are not adequate. RASKOR will automatically acquire a cooperative target within a window of 10 degrees el x 40 degrees az out to ranges of 60,000 feet. The required tracking accuracy is 1 degrees, and the range must de determined to an accuracy of 10 feet at ranges below 1,000 feet. In addition, the range rate must be computed to an accuracy of 3 knots. The system objectives are to be met using three GaAs injection laser transmitters--a 60 watt transmitter for long-range acquisition and track and two 2-watt transmitters for short-range operation.
