本文研究了同时发射和同时接收水平偏振和垂直偏振的天气雷达测量结果，指出同时发射偏振度（<sub>ps</sub>）与同时发射偏振相关系数（ZDRs和ρ<sub>hys</sub><i>）和</i>差分反射率（ZDRs）有关。<i></i><sub></sub><i></i><i></i>我们评估了偏振度在天气雷达应用中同时发射的潜力。最后，我们探讨了双极化天气雷达的发射极化状态调整为圆极化的后果。
We consider weather radar measurements at simultaneous transmission and simultaneous reception of horizontal and vertical polarizations and show that the degree of polarization at simultaneous transmit (<i>p</i><sub>s</sub>) is related to differential reflectivity and copolar correlation coefficient at simultaneous transmit (namely, <i>Z</i><sub>DR</sub><i>s</i> and ρ<sub>hy</sub><i>s</i>). We evaluate the potential of degree of polarization at simultaneous transmit for weather radar applications. Ultimately, we explore the consequences of adjusting the transmit polarization state of dual-polarization weather radars to circular polarization.
