Patent number: 8981869Abstract: A multilayer circuit board assembly includes one or more radio frequency (RF) interconnects between different circuit layers on different circuit boards which make up the circuit board assembly. The RF interconnects can include one or more RF matching pads which provide a mechanism for matching impedance characteristics of RF stubs to provide the RF interconnects having desired insertion loss and impedance characteristics over a desired RF operating frequency band. The RF matching pads allow the manufacture of circuit boards having RF interconnects without the need to perform any back drill and back fill operation to remove stub portions of the RF interconnects in the multilayer circuit board assembly.Type: GrantFiled: January 27, 2010Date of Patent: March 17, 2015Assignee: Raytheon CompanyInventors: Angelo M. Puzella, Joseph M. Crowder, Patricia S. Dupuis, Michael C. Fallica, John B. Francis, Joseph A. Licciardello

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.

Patent number: 6100841Abstract: A compact RF monopulse receiver circuit having a relatively low noise figure which is particularly useful for operation in the millimeter wave frequency range is described. The compact monopulse receiver finds use in small projectile and small missile applications. Also, a combination of transmit signal protection circuitry and receiver circuit architecture allows the RF monopulse receiver circuit to operate in a missile or other projectile which utilizes high RF power transmit signals. The RF monopulse receiver circuit can directly provide a radiation pattern for target detection and tracking or alternatively, the RF monopulse receiver circuit can function as a monopulse feed circuit which can be used, for example, in a quasi-optically fed reflector antenna.Type: GrantFiled: June 19, 1998Date of Patent: August 8, 2000Assignee: Raytheon CompanyInventors: John Toth, Michael J.
