<p>PURPOSE:To continue a phase correcting operation even when a monitor for measuring a phase of a phased array radar becomes defective so that a power source is once turned OFF. CONSTITUTION:A beam controller 5A for controlling phase shifting amounts of a plurality of phase shifters of a phased array antenna based on phase correction data to be output from a monitor 6 has a RAM 522 for temporarily storing phase correction data, an EEPROM 523 for storing the phase correction data stored in the RAM 522, and a memory controller 524 for controlling the RAM 522 and the EEPROM 523. When the monitor 6 becomes defective so that the power source of the controller 5A is once turned OFF, a phase shifting amount is controlled by using the correction data stored in the EEPROM 523.</p> |
