A polarization and channel calibration technique used in dual polarization eight channel mono-pulse radar system is introduced in this paper. System error model is proposed. The method is based on equipments test and microwave chamber test without any calibrators. Cross-polarization error and amplitude-phase imbalances between different transmitting and receiving channels as well as different antenna...
A wide tuning range LC VCO with auto amplitude control is designed in 0.13-μm CMOS. Phase noise optimized design for the wide tuning range VCO is discussed and a PVT insensitive digitally reconfigurable auto amplitude calibration (AAC) circuit is used to stabilize the phase noise in the whole wide band. The proposed AAC circuit with a code estimated FSM provides faster operation to get the optimum...
A transceiver which includes four transmitting channels, four receiving channels and four calibration channels used for Ku band digital monopulse radar system is introduced in this paper. This design may improve the performance of transmitters and receivers. The channel calibration can be carried out easily with the built-in calibration path. The amplitude and phase consistency between different channels...
A base band sum-difference scenario used in digital monopulse end-guidance radar system is introduced in this paper. A method used to measure the microstrip array antenna pattern at base band is presented. The result shows that the antenna pattern in this design has much better performance at null-depth of difference beam than the traditional design. The angle measurement performance based on the...
