Claim 1
Independent Claim
119 words
A PULSED RADAR SYSTEM COMPRISING MEANS FOR TRANSMITTING SUCCESSIVELY DIFFERENT MUTUALLY DISTINGUISHABLE PULSES IN A PREDETERMINED PERIODICALLY REPEATED SEQUENCE OF SUCCESSIVELY DIFFERENT PULSES; MEANS FOR RECEIVING ECHO SIGNALS REFLECTED BY TARGETS; PULSE LENGTH DISCRIMINATING MEANS FOR SEPARATING THE SUCCESSIVELY DIFFERENT ECHO SIGNAL PULSES OF EACH SEQUENCE IN DIFFERENT ONES OF A CORRESPONDING NUMBER OF SIGNAL CHANNELS; ECHO SIGNAL UTILISATION MEANS; AND MEANS FOR SWITCHING THE OUTPUTS OF THE DIFFERENT CHANNELS IN TURN TO SAID ECHO SIGNAL UTILISATION MEANS, EACH SAID CHANNEL BEING SWITCHED TO SAID UTILISATION MEANS FOR A TIME PERIOD NOT EXCEEDING THE TIME INTERVAL BETWEEN THE TRANSMISSION OF THE DISTINGUISHABLE PULSE TO WHICH THAT CHANNEL IS APPROPRIATE AND THE TRANSMISSION OF THE NEXT PULSE IN THE SEQUENCE.
