Abstract
A system for controlling the flight of a missile by the use of coded radar signals. A ground level radar transmits coded signals in the form of a phase modulated radar signal. Each coded signal represents a particular guidance command which is received by the missile and "filtered" out of the radar signal by a surface acoustic wave correlator. The correlator detects the code in the signal and in turn energizes a control circuit which operates a control surface on the missile.
Claims4
A remote control system for guiding a missile comprising:
- a radar system including means for transmitting phase-coded command signals, one phase-coded signal for each command;
- means installed in the missile for receiving said command signals;
- means for decoding the command signal,
- said decoding means comprising a plurality of surface-acoustic-wave correlators, one correlator for each command signal, and means for deciphering the output of the correlators to determine which of the correlators produced a response;
- and,
- means for operating a control surface on the missile in response to the decoded command signal.
