摘要: A method, an antenna, and a system for determining positions reflection points using microwaves. An electromagnetic wave signal is generated at defined frequency, transmitted by antenna unit (30). The (30) includes transmitter plurality of receiver antennas, separated known spacing perpendicular to main line sight (z) devised receive reflected portions the wave. Phase comparator means are connected control phase operable calculate angle (φ,θ) point (P) from detected difference between least two antennas said distance (r) dependent on frequency.
