Abstract
Disclosed is a system for receiving a signal from a known direction and rejecting interfering signals arriving from other directions. The system makes use of an antenna unit having multiple output ports, each responsive to signals from a different selected region of space. The output port correspondong to the region of space, which includes the direction of the desired signal, is coupled directly to an output combiner while the antenna ports corresponding to the remaining regions of space are combined to form a reference signal. Means are provided to form a correction signal in response to the reference signal and output signal for suppressing interfering signals arriving from other than the selected region of space.
