A multi-faced radar system illuminates a common area of space by radiating a first signal at a first frequency from a first antenna face and a second signal at a second frequency from a second antenna face and cooperatively processes the first and second signal returns on the first and second antenna faces. A processor combines first signal energy from the first and second faces and combines second signal energy from the first and second faces. The processor then combines the aggregate first and second signal returns. The cooperative processing of the first and second signals on the first and second antenna faces increases signal sensitivity and dramatically reduces the time on target required for relatively high scan angles,

1. A radar system, comprising:a first antenna face for generating a first plurality of beams to illuminate a first region of space with a first signal having a first frequency; a second antenna face for generating a second plurality of beams to illuminate a second region of space with a second signal having a second frequency that differs from the first frequency by a predetermined amount, wherein a first one of the first plurality of beams overlaps with a first one of the second plurality of beams to form an overlap region when a scan angle of the first one of the first plurality of beams is greater then a predetermined threshold for minimizing dwell time at scan angles greater than the predetermined threshold; a first transmit/receive module coupled to the first face; a second transmit/receive module coupled to the second face; and a processor coupled to the first and second transmit/receive modules, wherein the first face receives first and second signal energy reflected from a target in the overlap region and the second face receives first and second signal energy from the target in the overlap region, and the processor cooperatively processes the first and second signal returns from the first and second antenna faces.
