Small-size ADS-B satellite-borne simulation multi-beam receiving antenna

Abstract

The invention provides a small-size ADS-B satellite-borne simulation multi-beam receiving antenna. The small-size ADS-B satellite-borne simulation multi-beam receiving antenna comprises a receiving antenna array, a radio frequency receiving module and a multi-beam network, wherein the receiving antenna array is arranged outside a satellite and is used for receiving an incoming signal from a ground spacecraft, the radio frequency receiving module is arranged in the satellite and is used for filtering and amplifying the incoming signal, the multi-beam network is arranged in the satellite and isused for performing power division, phase shift and power combination on the signal filtered and amplified by the radio frequency receiving module. The small-size ADS-B satellite-borne simulation multi-beam receiving antenna provided by the invention is low in profile, light in weight and small in antenna size envelope, beam coverage with a visual angle being + / -55 degrees can be achieved, the requirements of a microsatellite on antenna volume, weight and size envelope are met, meanwhile, the requirement of a chain on high gain and wide beam cover range is met, and the small-size ADS-B satellite-borne simulation multi-beam receiving antenna is suitable for cubic star with a size being 6U or above.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a miniaturized ADS-B satellite-borne analog multi-beam receiving antenna. Background technique [0002] Automatic Dependent Surveillance-Broadcast (ADS-B) is a new technology based on satellite positioning that can complete air traffic surveillance and information transmission. ADS-B technology refers to the installation of the ADS-B system as a payload on a low-orbit micro-satellite, and the use of the satellite's wide coverage to achieve effective monitoring and tracking of civil aviation aircraft in the coverage area. Further, through the low-orbit satellite network composed of several micro-satellites, seamless coverage of the global airspace is realized. The ADS-B system can provide the detailed position and flight status information of the aircraft, and is the core technology for the improvement of the surveillance capability of my country's next-generation air traffic co...
