We have developed a suppression section forming method in a directivity pattern based on a multiplication of multiple weighted sum circuit outputs. In this method, the suppression section can achieve a high suppression performance. However, it lacks flexibility in designing directivity other than the suppression direction. In this study, we set multiple constraints on the array sensitivity to the direction like a filter design scheme. In our proposal, multiple constraints for WSCs are increased, an improvement of directivity design freedom is attempted. |
