Claim 1
Independent Claim
153 words
A RADIO NAVIGATIONAL SYSTEM INCLUDING AT A TRANSMITTING STATION A NARROW BEAM DIRECTIONAL TRANSMITTING AERIAL ARRANGED TO CREATE A SCAN OF ITS RADIATION PATTERN, THE RADIATION PATTERN BEING SYMMETRICAL IN THE DIRECTION OF ITS MOVEMENT, MEANS FOR TRANSMITTING ONE RADIO-FREQUENCY PULSE SIGNAL FROM THE DIRECTIONAL TRANSMITTING AERIAL FOR EACH REGULAR ANGULAR INCREMENT OF SCAN OF THE RADIATION PATTERN, MEANS FOR TRANSMITTING A DISTINCTIVE RADIO-FREQUENCY SIGNAL AT A DATUM ANGLE OF SCAN, AND AT A RECEIVING STATION MEANS FOR COMPUTING THE DIFFERENCE IN THE NUMBER OF PULSE SIGNALS HAVING AN AMPLITUDE GREATER THAN A PREDETERMINED AMPLITUDE RECEIVED BETWEEN LEADING EDGE OF SAID RAIDATION PATTERN AND BEFORE THE DISTINCTIVE SIGNAL AND THE NUMBER OF PULSE SIGNALS HAVING AN AMPLITUDE GREATER THAN THE PREDETERMINED AMPLITUDE RECEIVED BETWEEN THE DISTINCTIVE SIGNAL AND TRAILING EDGE OF SAID RADIATION PATTERN WHEN THE DISTINCTIVE SIGNAL IS RECEIVED DURING THE RECEIPT OF A SUBSTANTIALLY REGULAR SUCCESSION OF THE SAID PULSE SIGNALS.
