Abstract
A method is presented for solving DOA tracking problems when there are correlated signals present. The new technique, which is called signal vector randomization, can be used to efficiently eliminate any correlation in the signals. This allows fast tracking methods to be used without any modification. The method is shown to be as effective as the spatial smoothing method
