Abstract

The invention provides a receiving channel automatic leveling method and a judging method and a leveling system thereof with the automatic leveling condition and belongs to the field of blank pipe onboard anti-collision systems. A standard signal source is generated in a receiving machine, and difference between amplitude values measured when signals of a standard signal source pass each receiving channel is kept in the set error range by adjusting the configuration parameters of a receiving machine. Manual operation and equipment matching are saved, leveling accuracy and leveling efficiency are improved, the channel leveling requirement is met before equipment delivery, and equipment installation out-field maintenance requirement can be met.

Description

technical field [0001] The present invention relates to an automatic leveling method for a receiving channel, a method for judging its automatic leveling conditions and a leveling system, in particular to an automatic leveling method for a receiving channel suitable for airborne collision avoidance systems in the field of air traffic control It also has a judging method for automatic leveling conditions and a leveling system. Background technique [0002] The airborne collision avoidance system is the most effective air transport safety guarantee equipment necessary to prevent the dangerous approach of air planes and avoid air-to-air collision accidents. Based on the principle of secondary radar, it sends only C-mode all-call inquiries and S-mode roll call inquiries to nearby aircraft equipped with air traffic control transponders, receives and processes C-mode and S-mode response signals, and generates target tracks; according to The target aircraft performs threat detecti...
