Abstract
Automatic control circuitry for maintaining the frequency of a first local oscillator in a radar receiver at a predetermined offset frequency with respect to the frequency of either transmitted signals from a radar transmitter or echo signals from a target is disclosed. The disclosed circuitry operates as a discriminator when the frequency of the first local oscillator is different from the predetermined offset frequency and as a 'phase lock' loop when the frequency of the first local oscillator is the same as the predetermined offset frequency.
