A new modified ultra-wideband in-phase power divider for frequency band 2–18 GHz has been designed, successfully fabricated and tested. The power divider is based on the coupled strip-lines. Only two balanced resistors are used in the proposed structure. So the power divider has very low insertion loss. The capacitive strips placed over the resistors have been introduced in the suggested design as...
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.
Monopulse radar is widely used for its high-precision angle measurement and powerful anti-jamming performance. Because the components of radar system are not ideal, the radar measurement accuracy is reduced. According to the structure of sum and difference patterns phase-comparison two-dimension monopulse radar system, the system is divided into three parts, which include the circuit from antenna...
