To improve performance of acoustic vector sensors for direction-of-arrival（ DOA） estimation

a new algorithm based on TAMVDR is used in vector line array signal processing

called VTAMVDR. The principle of VTAMVDR is analyzed theoretically. In the model

complex-weighted vector is introduced to time-domain wideband signals through Hilbert transformation. Thus

the narrow-band division and blocking process are avoided

and the data length required to obtain stable optimum weighted vector is far less shorter than frequency-domain MVDR method. The result of simulation and sea trial data analysis result show that

compared with frequencydomain MVDR method

VTMVDR algorithm has better performance

with higher resolution and narrower beam angle

and has better performance of detection.
