Method and apparatus for direction-of-arrival tracking

Arrival direction tracking method and apparatus for its application in the base station shaped beam. Proposed a direction-tracking method even when the track intersecting direction of arrival, can quickly track the direction of arrival of radio waves. By this tracking method, using a previous direction updating state vector at an instant to predict the current direction updating direction of arrival time of a state vector to calculate the direction of arrival of the provisional estimated values ​​using the observer, the state vector by the direction of arrival and arrival direction of the velocity and acceleration of the configuration, in addition, calculates the current direction updating time state vector based on the provisional estimates the predicted state vectors, and the predicted value of the arrival direction, through the estimated value of the state vector calculating the arrival direction.
