METHOD FOR ALLOWING A TRACKING RADAR TO DETECT A TARGET AT A LARGE DISTANCE, WITHOUT AMBIGUITY, BY MEANS OF HIGH-FREQUENCY PULSES

摘要

P THE INVENTION CONCERNS A PROCESS FOR ALLOWING TRACKING RADAR TO DETECT A TARGET AT A LARGE DISTANCE, WITHOUT AMBIGUITY, BY MEANS OF HIGH FREQUENCY PULSES. /P P THE CARRIER FREQUENCY OF VARIOUS EMITTED PULSES FROM ONE PULSE TO ANOTHER IN THE SAME SERIES OF PULSES. THE NUMBER OF THESE FREQUENCIES IS CHOSEN IN RELATION TO THE TARGET DISTANCE, MEASURED CONTINUOUSLY, AND IT REMAINS CONSTANT AS LONG AS THIS DISTANCE IS LESS THAN A CERTAIN VALUE. WHEN IT EXCEEDS THIS VALUE, THE NUMBER OF CARRIER FREQUENCIES IS CHANGED AND THE PULSES ARE TRANSMITTED AS A SERIES INCLUDING THIS NEW NUMBER OF FREQUENCIES. /P P FIELD OF APPLICATION: PURSUIT RADARS. / P
