Description

Technical Field

[0001] The present invention relates to the technical field of microwave landing systems, and in particular to an anti-interference airborne receiving device for microwave landing systems. Background Art

[0002] The basic working principle of the microwave landing system is that the airborne equipment receives the guidance signal transmitted by the ground equipment, and obtains the position information of the aircraft relative to the runway (azimuth, elevation, distance, etc.) after processing. The pilot autonomously controls the aircraft to land safely according to the instructions of the aircraft instruments. The microwave landing system consists of an azimuth station, an elevation station, a precision rangefinder and an airborne receiver. The azimuth station and the elevation station transmit scanning signals into the air. After the airborne receiver receives the "going" and "returning" scanning signals, it obtains the position of the aircraft in space by measuring the time interval between the two beam signals.
