Abstract :
A single-port adaptive DOA estimation based on temporally-correlated array signal samples is proposed. Temporal correlation is created by lowering the receiver bandwidth and/or increasing the weighing rate. The proposed technique can estimates the DOAs of multiple independent sources in very low SNR levels. The proposed technique is compared with MUSIC and single-port beam space MUSIC.
