Sensor array processing using pseudo-noise resampling




array signal processing, DOA estimation, estimator bank, resampling root-swap


The problem of threshold performance improvement of direction finding using estimator bank approach is considered. The modified unitary Root-MUSIC estimator and pseudo-noise resampling are used to form the estimator bank. The classification of roots of the modified unitary Root-MUSIC polynomial based on their proximity to the unit circle is used on the final step of proposed approach.
