Patent ID: 7605743

Claim:
A material-penetrative positioning method for locating a measurement signal on walls, ceilings, and floors, comprising steps of: transmitting a measurement signal ( 22 , 122 ) in the gigahertz frequency range using a high-frequency transmitter ( 20 , 120 ) positioned at a first surface ( 14 ) of a material ( 10 ) to penetrate the material at least once; moveably positioning a reflecting means ( 126 ) at a second surface ( 16 ) of the material ( 10 ) to reflect a portion of the measurement signal ( 22 , 122 ) that has penetrated; and receiving a portion of the measurement signal portion reflected from the reflecting means ( 126 ) using a high-frequency receiver ( 24 , 124 ) positioned at the first surface ( 14 ) of the material ( 10 ) to locate a penetration position ( 18 ) of the measurement signal.
