大口徑天線(xiàn)校正網(wǎng)絡(luò)中功率和相位分析
[Abstract]:Generally speaking, calibration network analysis only considers the working state of transmission correction and receiving correction. However, for the large aperture array antenna, in addition to the correction state, in the normal working state of the system, due to the large aperture of the array, Often, the phase of the feed port varies greatly, and even the phase inversion occurs. Therefore, when designing the calibration network, we must demonstrate the influence of various working states of the whole radar system on the correction network, and avoid the phenomenon that the local power in the correction network is too large and the network is destroyed. The circuit model is established by using ADS software to correct the distribution of power and phase in the network when analyzing the various working states of radar system. Through simulation and analysis, we can clearly grasp the situation of the power bearing in various parts of the correction network, and effectively improve the reliability of the design of the correction network. The analytical results are accurate, reliable and effective.
