  • RF gun barrel detection system
    Patent number: 8890745
    Abstract: 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.
