Pure Aloha Approximation to Mode S Transponder Throughput Modelling

Popis výsledku v původním jazyce

An aeronautical surveillance infrastructure in technologically developed regions is primarily based on cooperative systems. A core part of the infrastructure consists of Secondary Surveillance Radars (SSR), Multilateration systems (MLAT) and an Automatic Dependent Surveillance-Broadcast (ADS-B). Due to the inherent nature of the cooperative technologies, the on-board transponders and the 1030/1090 MHz frequencies are shared among all the systems. The collective usage combined with growing air traffic and the necessity for extracting downlink airborne parameters using Mode S result in large demands on RF spectrum and on the on-board equipment. The increasing occupancy goes hand in hand with increasing probability of an interrogation interference. The prospect of a surveillance information loss highlights the need to analyse and possibly predict the behaviour of 1030/1090 MHz environment by air navigation service providers. This paper focuses on a plausibility of approximating the SSR Mode S (selective) interrogation sequences in multi-radar coverage to a Pure Aloha protocol which incorporates a mutual independence of radar systems and an interrogation retransmission. The feasibility of the approximation is evaluated using simulation of a typical interrogation sequence while analysing the Mode S transponder throughput. The Pure Aloha model parameters to fit the selected interrogation sequence are devised.
