Claims

3. IN COMBINATION, A FIRST STATION AND A SECOND STATION MOVABLE WITH RESPECT TO EACH OTHER, MEANS LOCATED IN SAID FIRST STATION COMPRISING A CONTINUOUS WAVE RADAR TRANSMITTER FOR GENERATING AND TRANSMITTING A FIRST CARRIER SIGNAL AND A FIRST SUBCARRIER SIGNAL TO SAID SECOND STATION, MEANS LOCATED IN SAID SECOND STATION FOR RECEIVING SAID FIRST CARRIER SIGNAL AND SAID FIRST SUBCARRIER SIGNAL AND GENERATING A SECOND CARRIER SIGNAL AND A SECOND SUBCARRIER SIGNAL, SAID MEANS FURTHER INCLUDING MEANS FOR ADJUSTING THE PHASE OF SAID SECOND CARRIER SIGNAL IN RESPONSE TO THE PHASE OF SAID FIRST CARRIER SIGNAL AND MEANS FOR ADJUSTING THE PHASE OF SAID SECOND SUBCARRIER SIGNAL IN RESPONSE TO THE PHASE OF SAID FIRST SUBCARRIER SIGNAL WHEREBY SAID SECOND CARRIER SIGNAL AND SAID SECOND SUBCARRIER SIGNAL HAVE THE SAME PHASE RELATIONSHIP AS SAID RECEIVED FIRST CARRIER SIGNAL AND SAID FIRST SUBCARREIR SIGNAL,
