- PROBLEM TO BE SOLVED: To provide a method and system using transmission of an electromagnetic signal in order to determine the positions of reflection points by detecting the signals reflected at the reflection points in space. ; SOLUTION: The present invention provides a method, antenna, and system for defining the positions of the reflection points using microwave. The electromagnetic signal is generated at a determined frequency, and is transmitted by an antenna unit. The antenna unit comprises a transmitting antenna, and many receiving antennas that are separated at a known interval in the direction perpendicular to the main visual axis and are designed to receive a part of the reflected wave of the transmitted wave. A phase comparing means is connected to the transmitting antenna and receiving antennas, and a control unit connected to the phase comparing means can calculate an angle to the reflection points and calculate the distances to the reflection points. ; COPYRIGHT: (C)2007,JPO&INPIT

Patent (populärvet., debatt m.m.)abstract
- A method, an antenna, and a system for determining positions for reflection points using microwaves. An electromagnetic wave signal is generated at a defined frequency, and transmitted by an antenna unit the antenna unit includes a transmitter antenna and a plurality of receiver antennas, separated by a known spacing perpendicular to a main line of sight and devised to receive reflected portions of the transmitted wave. Phase comparator means are connected to the transmitter antenna and the receiver antennas, and a control unit connected to the phase comparator means is operable to calculate an angle to a reflection point from detected phase difference between at least two receiver antennas and the spacing between said at least two receiver antennas, and to calculate a distance to the reflection point from detected phase difference between the transmitter antenna and a receiver antenna dependent on the frequency.
