Method and apparatus for detection of an electromagnetic signal reflected by an object

Abstract From the Canadian patent

For detection of an electromagnetic signal which is , transmitted from a transmitting antenna by means of at , least two at least essentially identical receiving antennas whose sensitivity curve has a maximum with falling flanks as well as sidelobes adjacent to it with sensitivity increased again at a reception angle symmetrically with respect to a basic alignment, with angle determination for an object which reflects the transmitted signal being carried out by the two receiving antennas by phase determination in an unambiguity area whose boundaries are predetermined by the distance between the receiving antennas the distance is , chosen such that the boundaries of the unambiguity …
