First Claim
4. A SYSTEM FOR DETERMINING THE DISTANCE BETWEEN AN AIRBORNE RECEIVER AND AN AIRBORNE RADIATING SOURCE COMPRISING RADIATION RECEIVING MEANS IN THE RECEIVER HAVING AT LEAST ONE DEGREE OF FREEDOM, STORAGE MEANS CONNECTED TO THE RADIATION RECEIVER TO RECORD SIGNALS INDICATIVE OF THE ANGLES AT WHICH RADIATIONS ARE RECEIVED FROM THE RADIATING SOURCE, SAID ANGLES FORMED BY THE INTERSECTION OF LINES BETWEEN SAID RECEIVING MEANS AND RADIATING SOURCE AND A LINE PARALLEL TO THE SURFACE OF THE EARTH, FIRST GENERATING MEANS CONNECTED TO THE RECEIVING MEANS TO PROVIDE A SIGNAL INDICATIVE OF THE COSINE OF THE ANGLES AT WHICH RADIATION IS RECEIVED, SECOND GENERATING MEANS CONNECTED TO THE STORAGE MEANS TO PROVIDE A SIGNAL INDICATIVE OF THE SINE OF THE DIFFERENCE BETWEEN TWO ANGLES AT WHICH RADIATION IS RECEIVED, ALTIMETER MEANS TO DETERMINE THE ALTITUDE OF THE RECEIVER, THIRD GENERATING MEANS CONNECTED TO THE ALTIMETER AND FIRST GENERATING MEANS TO PROVIDE A SIGNAL PROPORTIONAL TO THE PRODUCT OF THE ALTITUDE AND THE COSINE OF THE RECEIVING ANGLE, MEANS TO MULTIPLY THE OUTPUT OF THE SECOND GENERATOR BY A FACTOR PROPORTIONAL TO THE DESIRED DISTANCE, MEANS TO COMPARE THE PRODUCT OF THE ALTITUDE TIMES THE COSINE OF THE RECEIVED ANGLE WITH THE PRODUCT OF THE DESIRED DISTANCE AND THE SINE OF THE DIFFERENCE BETWEEN THE ANGLES, AND MEANS TO VARY THE FACTOR BY WHICH THE OUTPUT OF THE SECOND GENERATOR IS MULTIPLIED UNTIL THE OUTPUT OF THE COMPARISON MEANS IS A MINIMUM.
