Joint frequency and bear estimation based on acoustic vector-sensor
Zhang Guangbin · Journal of Shaanxi Normal University · 2005
A single acoustic scalar-sensor has no ability to estimate the object direction, but a small vector-sensor has it. A new method for joint estimation frequency and angle of arrival based on only one acoustic vector sensor is proposed in this paper. In contrast to the LS-ESPRIT and TLS-ESPRIT method, the arithmetic has less computation because of the one eigen-decomposition and the automatically paired parameters. The simulation results verify the efficacy of the method.
