Secondary surveillance radar communications, which purpose is to acquire aircrafts critical information, are on the brink of spectrum saturation. This is the result of dense traffic and different waveforms modulation schemes, used in Modes A/C and Mode S communication layers, which share the same unscheduled propagation bandwidth. This leads to a significant rise of packet collision probability. In this context, we propose an original single-channel receiver able to process the simultaneous reception of several Mode A/C and S packets. The decoding strategy relies on the successive interference cancellation principle, comprising original detection, decoding, and reconstruction processes. The relevance of our proposition is validated by numerical simulation and confirmed through field experiments on automatic dependent surveillance-broadcast signals reception.
