Abstract
A receiver array in accordance with the reception principle of synchronous demodulation, in which a controllable oscillator array is pre-synchronized to a set value for the oscillator frequency by a digital first control circuit having a reference frequency source during a pre-synchronization phase, and a heterodyne signal derived from the oscillator frequency is then synchronized with phase locking to the received useful signal by switching the oscillator control input to an analog second control circuit.
