Problems solved by technology

In this way, when the density of C-mode aircraft around the aircraft is high, the electromagnetic environment will be very complicated, and it is easy to generate confusion and synchronization interference, which will affect the transmission of air communication links, so it is necessary to propose improvements

Embodiment Construction

[0015] Attached below Figure 1-3 An embodiment of the present invention is described.

[0016] The C-mode transponder only reports the altitude of the aircraft, adopts the broadcast inquiry / response form, and conducts one question and multiple answers. For the same inquiry, if multiple C-mode transponders answer at the same time in the adjacent airspace, the air traffic anti-collision processor will It is impossible to identify the location of the intruder, and it is very easy to interfere. Adopt the method of low-pitched call inquiry, actively initiate multiple inquiries, use different inquiry power, suppression signal, and receiving sensitivity in different directions, cover the range that can be monitored around the aircraft layer by layer, and inquire about the aircraft reception in the area covered by the signal After the inquiry, respond, and the aircraft in the area where the inquiry signal is not covered or the area where the inquiry signal is suppressed does not nee...

Abstract

Provided is a method for achieving C-mode low-voice calling of a traffic collision avoidance system. Layered and different-beam inquiry is conducted on nearby airspace by controlling inquiry power, the number and density of C-mode inquiry responses are effectively reduced, and the airspace electromagnetic environment around an airplane is simpler. After the scheme is adopted, secondary radar can be higher in efficiency and more reliable in the communication process, the air traffic environment sensory capacity is greatly improved, and the reliability and effectiveness of air traffic early warning and collision avoidance are enhanced.

Description

technical field [0001] The invention belongs to the technical field of airborne equipment, and in particular relates to a method for realizing a low voice call in C mode of an air traffic collision avoidance system, which is used for early warning and collision avoidance of air traffic. Background technique [0002] With the development of secondary radar technology and the increase in the demand for airborne communication content, the use of airborne secondary radar is gradually transitioning from A-mode transponders to C-mode and S-mode transponders. At present, the most used airborne transponders are S mode and C mode transponders, and their response signals conform to the S mode transmission format and the C mode transmission format respectively. Today's air traffic control ground stations and air traffic collision avoidance systems can complete the inquiry and response reception of C mode and S mode signals. Mode S transponders are used to transmit information such as ...
