METHOD FOR INTERFEROMETRIC RADIOGONIOMETRY AND RADIOGONIOMETER FOR IMPLEMENTING SAID METHOD

摘要

P THE RADIOGONIOMETER HAS AN AQUATIC NETWORK COUPLED BY AN ANTENNA SWITCH 10 WITH TWO TWO TRUNK LINES WITH CONTROLLABLE DELAYS 11 AND 12. THESE DELAY LINES ARE RELATED TO THE INPUTS OF A HYBRID COUPLER AT QUATRATURE13, THE OUTPUTS DELIVERING SIGNALS FOR COMBINING SIGNALS PRESENT ON THEIR TWO ENTRIES. THE COUPLER OUTPUTS ARE ALTERNATELY CONNECTED BY A SWITCH14 TO EACH OR OTHER OF THE INPUTS OF TWO RECEIVERS15 AND 16. THESE RECEIVERS DELIVER TO A MANAGEMENT CIRCUIT20 TWO SIGNALS FROM WHICH A CHARACTERISTIC ERROR VALUE OF THE LATTER IS GENERATED DELAY IN ARRIVAL BETWEEN THE TWO ANTENNAS AND THE ARRIVAL ANGLE OF THE RADIO TRANSMISSION. THE MANAGEMENT CIRCUIT20 CONTROLS THE REVERSE RATE OF THE SWITCH 14 AND CONTROLS THE VARIATION IN THE DELAYS INTRODUCED BY THE DELAY LINES 11 AND 12 TO COMPENSATE THE TIME OF ARRIVAL. / P
