Abstract

The invention discloses a TCAS, mode S transponder and ADS-B integrated RF (radio frequency) system. The system comprises upper/lower antennas used for receiving and transmitting 1030MHz/1090MHz signals, a receiving module connected with the upper/lower antennas and used for conducting preselected filtering, amplitude limiting, amplification and radio-frequency signal processing on the 1030MHz and 1090MHz signals received by the upper/lower antennas, a signal processing module connected with the receiving module and used for conducting mode recognition and information decoding on the sampled signals and transmitting the decoded information to a data processing module for data processing, and a transmitting module connected with the receiving module and the signal processing module. According to the system, the TCAS, the mode S transponder, and the ADS-B are integrated, so that three functions are integrated, and one piece of equipment achieves three functions. The system is compact in structure and high in integration level.

Description

technical field [0001] The invention relates to a TCAS, S mode transponder and ADS-B integrated radio frequency system. Background technique [0002] At present, TCAS works based on the secondary surveillance radar inquiry / response method, and is widely used in the field of civil aviation as a key device to ensure flight safety. In the case of traffic conditions in the adjacent airspace of the aircraft, take the initiative to take evasive measures to avoid the occurrence of aircraft collisions in the air. After the local aircraft sends the inquiry signal, it receives the response signal from the target aircraft, analyzes the flight parameters such as the altitude, azimuth and distance of the target aircraft, and compares and calculates it with the track data of the local aircraft to obtain the rate of descent and distance change of the target aircraft. Rate and other information, judge the possibility of collision with the target aircraft, and give traffic advisory (TA) and...
