Abstract: Radio frequency (RF) detection and source localisation is a critical requirement for military and civilian applications. This paper implements a multistep RF detection technique in a software defined radio (SDR) platform, that starts by a fast energy detection then go through cyclostationarity feature detection to deal with low detected signals. This combination offers range potential to monitor wider area. The system relies on the received signal strength indication (RSSI) measurements to estimate the distance between the sensing system and the detected RF source. General-purpose SDR platforms offer more flexibility and cost efficiency, compared to dedicated localisation systems. It enables providing an embedded standalone system able to detect RF signals and to estimate the polar coordinates of the emitting source. Through experiments, we prove the validity of the proposed system for real applications.
