Abstract :
It is shown that for a slowly rotating sensor array accurate direction finding can still be achieved if the power method together with a rotation correction scheme is applied. The bearing estimation error curves along with input SNR, correlation of the ambient noise field, and incident direction of the source are also given. It also can be used for moving target tracking
