Abstract :
A base band sum-difference scenario used in digital monopulse radar system is introduced in this paper. The angle measurement error caused by the amplitude and phase imbalance of the receiving channels is also analyzed based on this system structure. A digital calibration method as well as the compensation result is represented.
