- In this paper, a new direction of arrival (DOA)
estimation algorithm, direction lock loop (DiLL), is proposed.
It has a similar concept to the delay lock loop (DLL) that is
used for synchronization. It estimates the DOA of a signal by
iterations, and can track the DOA of a moving source. The
DiLL scheme is found to track better than the DOA
estimation scheme based on the PASTd, and its performance
is less sensitive to the DOA of a signal than that of the DOA
estimation scheme based on the PASTd. The DOA estimation
accuracy and the tracking capability are demonstrated by
analysis and computer simulations.
