Patent number: 8451165Abstract: Described is a mobile radar system which provides both persistent surveillance and tracking of objects with adaptive measurement rates for both maneuvering and non-maneuvering objects. The mobile radar system includes a vehicle having mounted therein an active, electronically-steerable, phased array radar system movable between a stowed position and a deployed position and wherein the phased array radar system is operational in both the deployed and stored positions and also while the vehicle is either stationary or moving. Thus, the mobile radar system described herein provides for longer time on target and longer integration times, increased radar sensitivity and improved Doppler resolution and clutter rejection. This results in a highly mobile radar system appropriate for use in a battlefield environment and which supports single-integrated-air-picture metrics including but not limited to track purity, track completeness, and track continuity and thus improved radar performance in a battlefield.Type: GrantFiled: December 6, 2010Date of Patent: May 28, 2013Assignee: Raytheon CompanyInventors: Angelo M. Puzella, Steven T. Cummings, Joseph A. Licciardello, Jerome H. Pozgay, Stephen J. Pereira, Michael G. Sarcione, Peter D. Morico, James A. Roche, Jr.

Publication number: 20130088381Abstract: Embodiments of the concepts described herein are directed toward a common RF building block in the form of a monolithic assembly for an AESA array featuring a scalable RF design based on 2n:3 combining. The monopulse network building blocks are substantially identical, enabling an interchangeable sub-array architecture that is independent of position in the AESA aperture and receive sum channel sidelobe performance. In one embodiment, a passive Monopulse Beamformer may provide the passive 2n:3 RF coupling/combining network and an active Monopulse Processor may perform amplitude and phase weighting for the combined signals from the Monopulse Beamformer.Type: ApplicationFiled: October 6, 2011Publication date: April 11, 2013Applicant: Raytheon CompanyInventors: Angelo M. Puzella, Tunglin L. Tsai, John B. Francis, Donald A. Bozza, Kathe I. Scott, Patricia S. Dupuis
