摘要： (57)< Abstract > As for the advantage of being picked up according to the principle of this invention, by the invention person, as for speed of operation of the digital hardware inside the digital beamformer, for example it has the multiplex pha of the data signal, it is the technology that it improves and by treating the multiplex pha data next while N parallel addition passing. Interpolation deshimeshiyonhuiruta receives the multiplex pha data from N parallel addition pass, and the decrea ze and others re is offers the signal which has data rate (1/N) to output. According to this technology, as for speed of operation of the individual digital circuit in order to form necessary beam formation delay, as for augmenting by comparison with the general cost beam formation interpolation device it is not, as a result, effective data rate augments just coefficient N, the result that is brought and just coefficient N makes delay quantization error decrea. According to the principle of this invention, interpolation deshimeshiyonhuiruta is installed inside the beamformer in the place where are most convenient. Namely, this

after the part beam formation of one group of the reception channel, and before the formation of the last beam, is installed while beamformer treating. Rather than as for this approach, it is possible, to designate final beam formation as simple ones, it is run and in relatively low data rate, and with respect to the integrated circuit of the independent format which is repeatedly ud inside the beamformer becoming restriction to the circuit which circumstances well can provide signal processing of high rate is made possible.
