Abstract
An interferometric switched beam radar apparatus and method are disclosed. In one embodiment, a selected antenna of a planar array of beam forming antennas is activated with a substantially continuous frequency modulated transmit signal and a return signal is received from at least two return antennas that have a known offset distance relative to each other. Phase information is extracted from each return signal and used to present information regarding an operating environment to a user. Each beam forming antenna within the array may correspond to a particular viewing angle within the operating environment.
