Patent number: 8890745Abstract: A method of detecting an object includes receiving first reflected radio frequency (RF) signals from a region using an antenna and generating a first backscattering signature of the region from the first reflected RF signals. The method further includes receiving second reflected RF signals from the region subsequent to receiving the first reflected RF signals and generating at least one second backscattering signature of the region from the second reflected RF signals. The method further includes detecting a difference between the first backscattering signature and the second backscattering signature, and providing a warning indication in response to the difference between the first backscattering signature and the second backscattering signature.Type: GrantFiled: October 27, 2011Date of Patent: November 18, 2014Assignee: Raytheon CompanyInventors: Gary Fred Wahlquist, Kuang-Yuh Wu

Patent number: 8599095Abstract: According to one embodiment of the invention, a radome cover for an RF sensor has been provided. The radome cover comprises a first and a second ballistic layer, each ballistic layer having a ceramic layer. The two ballistic layers are sandwiched between at least two matching layers, and the matching layers are impedance matched to the ceramic layers. The radome cover provides ballistic protection for the RF sensor.Type: GrantFiled: January 18, 2008Date of Patent: December 3, 2013Assignee: Raytheon CompanyInventor: Kuang-Yuh Wu
