面向机载综合监视系统的ADS-B技术综述OACSTPCD

As an important new part of airborne integrated surveillance system(ISS),the automatic dependent sur-veillance-broadcast(ADS-B)system shows the advantages in surveillance and efficiency under the premise of en-suring flight safety,which leads to the development of future surveillance technology.Firstly,the system function and advantages and disadvantages of ADS-B system are introduced,and the technologies and products at home and abroad are organized.Then,from the perspective of ensuring flight safety and efficiency,the key technologies of ADS-B system are analyzed and summarized,and the technology connotation and difficulties are described in de-tail.Finally,the development trend of the technology is discussed and prospected in combination with the concept of next generation airspace operation,and four future development directions of ADS-B technology are proposed,which can provide the development direction for the development of ADS-B technology of airborne ISS,and pro-mote the development of ADS-B technology in practical operation and theoretical research.
