Assessing the Capacity of Air Traffic Control Secondary Surveillance Radar System

To assess the capacity of air traffic control (ATC) secondary surveillance radar (SSR) system in the first principle, using queuing theory model M/D/1/0, the paper constructed an analytical model for analyzing the relationship between the capacity and reply efficiency, rotation speed of antenna, beam width, time of signal processing, PRF or operation mode. The changes of capacity VS other parameters are simulated and calculated, the result shows that the model is valid and can be used to examine potential means of improving capacity.
