<p>PROBLEM TO BE SOLVED: To observe the arrival directions of correlative arriving waves with high precision by separating the arriving waves with high precision. SOLUTION: An SRA processing circuit 10 is equipped with a memory circuit 10b and element signals of antenna elements 1 to N are obtained by as many as the specific number of scans; and a correlation matrix arithmetic circuit 10a calculates correlation matrix values by the scans to find the mean correlation matrix value of the correlation matrix values by the scans and an SRA spectrum arithmetic circuit 10c based upon the mean correlation matrix value calculates the peak of an SRA spectrum.</p> |
