PROBLEM TO BE SOLVED: To improve the ratio of the signal and noise of receiving signal by a means integrating the receiving signal rotated in phase and a means setting the integrated signal to a single frequency band. SOLUTION: Adders 161-16p add mutual receiving signals of the phase correction values to output receiving signals to phase rotation circuits 171-17p and the circuits 171-17p output real components 171i-17pi to an adder 181 and imapinary parts 171q-17pq to an adder 182. A band-pass circuit 190 sets the complex signal outputs of the adders 181-182 to the single signal band on the complex frequency space. In order to obtain the envelop signal of phasing adding output, a circuit operating the sum square root of the outputs I, Q of the circuit 190 is connected. By this constitution, the phasing of extremely many parallel receiving signals can be performed with high accuracy inclusive phase connection and an apparatus can be simplified and can be reduced in cost. |
