204 words
A SYSTEM FOR SYNCHRONIZATION AND RANGE MEASUREMENT WITH A PLURALITY OF GUIDED MISSILES COMPRISING, A LAUNCHING DEVICE, MEANS ON THE LAUNCHING DEVICE FOR TRANSMITTING A SYNCHRONIZING PULSE TO EACH OF THE MISSILES, MEANS ON EACH OF SAID MISSILES FOR RECEIVING THE SYNCHRONIZING PULSE AND TRANSMITTING A RETURN PULSE TOWARD THE LAUNCHING DEVICE, MEANS ON THE LAUNCHING DEVICE FOR TRANSMITTING AN ILLUMINATING PULSE TOWARD A TARGET IN RESPONSE TO SAID RETURN PULSE, MEANS ON EACH OF SAID MISSILES FOR RECEIVING AN ECHO SIGNAL DIRECTLY FROM SAID TARGET, MEANS ON SAID LAUNCHING DEVICE FOR RECEIVING AN ECHO SIGNAL OF SAID ILLUMINATING PULSE FROM SAID TARGET AND RELAYING SAID ECHO SIGNAL TO EACH OF SAID MISSILES, AND MEANS ON EACH OF SAID MISSILES FOR COMPARING THE TIME FOR SAID RETURN PULSE TO TRAVEL TO THE LAUNCHING DEVICE PLUS THE TIME FOR SAID ILLUMINATING PULSE TO TRAVEL TO SAID TARGET PLUS THE TIME FOR AN ECHO OF SAID ILLUMINATING PULSE TO TRAVEL FROM THE TARGET TO SAID MISSILE, WITH THE TIME FOR SAID RETURN PULSE TO TRAVEL TO THE LAUNCHING DEVICE PLUS THE TIME FOR SAID ILLUMINATING PULSE TO TRAVEL TO SAID TARGET, TO GENERATE AN OUTPUT SIGNAL PROPORTIONAL TO THE RANGE BETWEEN THE MISSILE AND THE TARGET.
