Abstract
An interferometer arrangement includes an antenna array that receives radiation from a plane wave emitted by a transmitter, the radiation being incident on the array at an angle (θ). The array includes a plurality of antennas that provide output signals to a switching unit. The switching unit selects pairs of signals and passes them to a processor for processing. The processor is configured to produce an output signal that unambiguously indicates the value of the angle (θ).
