Abstract: A dual monopulse/interferometer antenna and radar system. In one example, the antenna includes an active electronically steered monopulse array, and is configurable into an interferometer mode which uses a subset of the array elements of each quadrant of the monopulse array. In one example, the RF feed network that combines signals received from each element in the array to produce monopulse return signals is modified in the interferometer mode to couple out the subset of array elements to produce return signals that are analyzed using interferometric processing.

Abstract: A millimeter wave power source module may include N submodules, each of which includes M circuit devices, where M and N are greater than one. Each circuit device may have an output connected to a corresponding radiating element. Each submodule may include a power divider having K input ports and M output ports, where K is a factor of M. Each input port may be coupled to a corresponding receiving element, and each output port may be coupled to an input of a corresponding circuit device. Each submodule may include a heat spreader for removing heat from the circuit devices. The power source module may include a combination RF feed network and heat sink. The combination RF feed network and heat sink may include a wavefront expander to expand the RF input wavefront along at least one axis, and to direct the expanded wavefront to the receiving elements of the N submodules. The combination RF feed network and heat sink may also include a heat exchanger thermally coupled to the heat spreaders of the N submodules.
