ARRAY ANTENNA RECEIVER APPARATUS AND RECEIVED SIGNAL CORRECTING METHOD

摘要

An array antenna receiver apparatus wherein no unnecessary radiations occur at an antenna part and even when the electric power level of a received signal is low, the received signal can be corrected with a high degree of precision. In this apparatus, only when the electric power level of a received signal captured by an antenna part (111) is low, a reference signal generating part (123) is activated to generate a reference signal. An error calculating part (122) compares information (S3) about the received signal, with which the reference signal has been multiplexed, with a correction signal (S4) to calculate an error of the received signal occurring therein due to a signal processing performed in a reception unit (110). Based on the calculated error of the received signal, the error calculating part (122) orders a received signal processing part (121) to compensate the received signal.
