RADIOGONIOMETER WITH TIME OF ARRIVAL, MONOCANAL, ADAPTED TO THE PROCESSING OF MODULATED SIGNALS IN A3J OR A1 AMPLITUDE

摘要

P THE RADIOGONIOMETER AT THE OUTPUTS OF ANTENNAS A AND B BASED ON THE INPUTS OF A HYBRID COUPLER WITH QUADRATURE 20 THROUGH CONTROLLED DELAY LINES 10, 11. THE COUPLER OUTPUTS ARE ALTERNATELY CONNECTED TO THE RECEIVER CHANNEL INPUT 40 AT A RHYTHM WHICH, AFTER A SIGNAL HAS BEEN DETECTED, IS BASED ON THE CHARACTERISTICS OF THIS DETECTED SIGNAL. WHEN THE RECEIVED SIGNAL IS A TYPE-TO-MODULE SIGNAL BY A SPEECH SIGNAL, THE TIME IS FUNCTION OF THE MELODY PERIOD MEASURED ON THE SIGNAL SO THAT THE MANAGEMENT CIRCUIT 50 GENES AN ERROR SIGNAL FUNCTION OF THE DISTANCE BETWEEN ENERGIES MEASURED ON INTERVALS EQUAL TO A PERIOD OF MELODY OF THE SPEECH SIGNAL. / P P THE INVENTION APPLIES, IN PARTICULAR, TO THE LOCALIZATION OF RADIOELECTRIC TRANSMITTER STATIONS TRANSMITTING SPEECH SIGNALS BY LATERAL BAND MODULATION. UNIQUE WITHOUT CARRIER. / P
