Adaptive antenna reception device having preferable reception quality of directivity beam from the initial stage

An adaptive antenna reception device, in which a signal processor is assigned to at least one incoming wave, and in said signal processor, signals that are received by a plurality of antennas are weighted by weights of each of said antennas that are determined by using a time average of a calculated value that is obtained by a prescribed computation from received signals of said plurality of antennas and then synthesized to further synthesize a plurality of incoming waves that have been received in a plurality of signal processors to obtain a desired signal;

• said adaptive antenna reception device comprising:
• an arrival direction detection unit for detecting the arrival direction of an incoming wave that is received by the signal processors from weights that have been determined by each signal processor in which at least a prescribed time interval has been secured for averaging time to find a time average;
• a reception quality acquisition unit for finding reception quality of a signal of an incoming wave that is received by weighting and synthesizing by each of said signal processors in which at least said prescribed time interval has been secured for averaging time;
• and
• an information collection/selection processor for selecting an initial beam direction in said signal processors that are to begin determination of weights that uses time average, based on each arrival direction and the reception quality in each of said signal processors in which at least said prescribed time interval has been secured for averaging time.
