Dual Channel Monopulse Automatic Phase Calibration Method

Combining the target flight and acquisition characteristics with tracking process, a phase calibration method is proposed through theoretical analysis of dual channel monopulse tracking system angular error demodulation principle. The key of that is a new real-time correction phase and real time cross coupling synthetic elimination scheme, which can quickly complete the phase calibration based on the method of radar terminal demodulation output cross coupling error angle voltage. It can use static beacons to achieve phase calibration and also can be in in the process of tracking flying object realizing real-time dynamic phase correction.
