<p>In an array antenna receiving apparatus employing a calibration system, a calibration time determining unit (111) determines an appropriate calibration time for a respective antenna radio receiving unit (104-1 to 104-N) on the basis of the determined voltage of the total received power inputted to the respective antenna radio receiving unit. Thereafter, a calibration signal processing unit (112) detects the phase/amplitude information of the calibration signals from multiple signals outputted by the antenna radio receiving units, on the basis of the longest one of the calibration times. Then, user signal processing units (108-1 to 108-M) correct the outputs from the antenna radio receiving units on the basis of the phase/amplitude information.</p> |
