Electromagnetic Detection Apparatus.
Abstract
An electromagnetic detection apparatus for sensing an object, has a transmitter for radiating electromagnetic energy toward the object. The apparatus also has an array of at least three spaced receiving antennas and one parasitic antenna. The parasitic antenna is spaced from and mounted alongside the array. Also included is a phase detection circuit for measuring the phase difference between signals received by one of the receiving antennas with respect to the other two. This apparatus can sense phase difference and correlate it to the azimuthal position of the object. (Author)
