STEREO RADAR TECHNIQUES

AN INVESTIGATION OF THE GEOMETRIC STRENGTH OF A STEREO SIDE LOOKING AIRBORNE RADAR (SLAR) MAPPING SYSTEM IS CONDUCTED. STEREO SLAR EQUATIONS WERE DEVELOPED ON THE BASIS THAT THE SLAR RANGE MEASUREMENT GENERATES A SPHERE AND THAT THE SQUINT ANGLE GENERATES A CONICAL SURFACE. A LEAST- SQUARES ADJUSTMENT IS USED FOR THE SOLUTION OF A TARGET POSITION OBSERVED FROM TWO AIR STATIONS. THE OPTIMUM FLIGHT CONFIGURATION FOR STEREO SLAR MAPPING WAS DETERMINED TO BE WITH AIR STATIONS AT THE SAME ALTITUDE, EQUIDISTANT ON EITHER SIDE OF THE TARGET POINT, AND MAKING A DIHEDRAL ANGLE OF 90 DEGREES AT THE TARGET POINT. IN THIS CONFIGURATION, THE ERROR PROPAGATION INTO THE HEIGHT COORDINATE AT THE TARGET POINT IS ON A 1 TO 1 BASIS RELATIVE TO THE ERROR IN BOTH THE RANGE MEASUREMENT AND IN THE AIR STATION HEIGHT MEASUREMENT. FLIGHT CONFIGURATIONS WITH BOTH AIR STATIONS ON THE SAME SIDE OF THE TARGET POINT WERE FOUND TO BE UNSUITED FOR MAPPING PURPOSES. /ASP/
