The invention relates to a monopulse radar system that aims to correct an amplitude error and a phase error developed between receiving channels and improve the accuracy of a detected angle. <??>To achieve the above aim, part of a transmit signal is supplied to respective channels on the receiving side through a signal transmission line for calibration (L1). At this time, the gains of a variable phase shifter (PS1) and a variable gain amplifier (VGA1) are adjusted so that an azimuth angle of a pseudo target, based on a signal for calibration, which is calculated by signal processing means (P1), reaches a predetermined angle. <IMAGE> |
