Abstract: |
1030/1090MHz frequencies are widely used in civil and military aviatio
ns. With fast growing of aircraft and equipment in airports, sharing of 1030
/1090 MHz frequencies and corresponding interferences are more and more compl
icated.
This paper provides an overview of different applications of 1030/1090MHz
frequencies, including Second Surveillance Radar(SSR), Automatic Dependent Surveilla
nceBroadcast(ADS-B), multilateration,Traffic Collision Avoidance System(TCAS), and Identification of Friend or Foe(IFF), Distance Measurement Equipment(DME) and Traffic Information ServicesBroadcast(TISB), etc. Usage situation and possible interferences of different systems are analyzed.It is pointed out that 1030/1090MHz monitoring and assessment of interference environment and applications are very important. |
