Single Channel Multiple Signal Classification Using Pseudo-Doppler

An algorithm is presented to determine the number and direction of multiple indistinguishable radio frequency emitters using a single channel circular antenna array. This algorithm combines pseudo-Doppler direction finding with the MUSIC algorithm. The theory is provided along with a simulation. The...

Zusammenfassung:An algorithm is presented to determine the number and direction of multiple indistinguishable radio frequency emitters using a single channel circular antenna array. This algorithm combines pseudo-Doppler direction finding with the MUSIC algorithm. The theory is provided along with a simulation. The simulation shows that the algorithm performs very well, with accuracy of better than one degree for typical scenarios, even with low signal to noise ratios.
