Single-antenna projection algorithm to discriminate super-imposed Secondary Surveillance Radar Mode S signals
Emilio G. Piracci, Nicolas Petrochilos, Gaspare Galati · 2007
This paper presents a novel, effective algorithm to discriminate and separate super-imposed SSR (Secondary Surveillance Radar) Mode S signals. Our goal is a blind separation of multiple SSR sources using a single channel receiver. Other algorithms perform sources separation exploiting space diversity or statistical properties, but with the practical inconvenience of the need for a multi-channel receiver. As today SSR stations are equipped with single-channel receivers (for Multilateration and Wide Area Multilateration applications, M-LAT, WAM) the proposed algorithm is aimed to be operationally useful.
