System for correlating the operating frequencies of two variable-frequency microwave generators

Two variable-frequency microwave generators, i.e. a coaxial magnetron producing outgoing waves and a voltage-controlled oscillator emitting a heterodyning signal for incoming waves of a radar transceiver, are continuously tuned by a pilot signal modifying their operating frequencies with a predeterm...

More Information
Summary:Two variable-frequency microwave generators, i.e. a coaxial magnetron producing outgoing waves and a voltage-controlled oscillator emitting a heterodyning signal for incoming waves of a radar transceiver, are continuously tuned by a pilot signal modifying their operating frequencies with a predetermined constant separation. To maintain this correlation, the tuning circuit of at least one microwave generator responds to the pilot signal through the intermediary of a read-only memory which, on being directly or indirectly addressed by that signal, emits stored setting instructions for the respective generator.
