ABSTRACT:
Reception signals received by first to fourth antennas11to14are sequentially selected one by one repeatedly in accordance with first to fourth switches31to34being controlled by first to fourth switch control circuits41to44, respectively, so as to be inputted to a signal shaping section60. The reception signals having been shaped by the signal shaping section60are sampled by a sample-and-hold section71and AD-converted by an AD converter72in accordance with a time at which the reception signals are sequentially selected. The resultant signals are converted into parallel signals by a serial-parallel conversion section73. Thus, the parallel signals are obtained as the reception signals of the first to the fourth antennas11to14.
