PROBLEM TO BE SOLVED: To simplify constitution even when the number of receiving elements is numerous. SOLUTION: Wave receivers Q1 -Qn output received signals a1 -an , a sampling circuit SPL samples the received signals a1 -an so as to output sampling signals Sn , a time axis correcting part TC delays the respective sampling signals Sn so as to output distribution time series signals fs distributed in time series, an addition part SUM adds the distribution time series signals fs to each other tournament-likely at every time so as to output an addition time series signal g, and a convolution circuit CNV performs convolution integration processing of the addition time seriers signal g and a convolution reference signal w so as to output a phasing signal h. |
