Metal–organic frameworks (MOFs) are one of the most promising advanced heterogeneous catalysts for the activation of peroxymonosulfate (PMS) to degrade organic contaminants in water, and have been extensively studied. However, MOFs in powder form usually have the disadvantage of poor separation and regeneration, making it significantly challenging for practical applications. In this study, ultralight...
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...
