Calibration signals which were generated in a signal generator 107 for calibration and to which frequency conversion was applied in a radio transmitting section 108 for calibration are made to be power levels in power level variable circuits 109-1 to 109-N so that power levels of calibration signals extracted in a signal processing section 106 for calibration become constant, and are multiplied by signals received at antenna elements 102-1 to 102-N in multiplex circuits 103-1 to 103-N.
