Abstract:
1. An adaptive array control device comprising: a first identification information generation section which applies first array processing to signals acquired in a plurality of sensors arranged in an array and calculates a relative ratio between a target signal and interference based on phase information to thereby acquire first identification information; a correction signal generation section which generates a correction signal, using the first identification information, for performing larger correction when target signal power is higher than interference power; a second identification information generation section which calculates a relative ratio between the target signal and the interference based on amplitude information to thereby acquire second identification information; a correction section which corrects the second identification information according to the correction signal to thereby acquire corrected identification information; and a control section which controls speed and accuracy of parameter adjustment in adaptive array processing using the corrected identification information.
