A microwave landing system with a range of + / - 90 degrees for the azimuthal guidance of the aircraft and a data frame range of 360 degrees.

摘要

A microwave landing system incorporates a set of antennas for the sequential transmission of guidance signals through a sequence of directions to enable the reception and decoding of the signals by an airborne receiver. Circuitry is included for the retransmission of a frame of the signals by a procedure wherein the directions of transmissions is altered so as to increase the guidance sector over which the receiver is effective.
