ABSTRACT:
The present invention provides that a monopulse radar system to correct an amplitude error and a phase error developed between receiving channels and improve the accuracy of a detected angle. A part of a transmit signal is supplied to respective channels on the receiving side through a signal transmission line for calibration. At this time, the gains of a variable phase shifter and a variable gain amplifier are adjusted so that an azimuth angle of a pseudo target, based on a signal for calibration, which is calculated by signal processing means, reaches a predetermined angle. In the monopulse radar system of the present invention, calibration work is simplified and an angular correction can be automated. The present monopulse radar system of the present invention is capable of coping even with variations in characteristic after product shipment due to environmental variations and time variations in parts characteristic.
