摘要
为拓展主被动微波探测系统遥感降水云雨的功能 ,使系统的原理先进性能有进一步的体现 ,将一套主被动双波段 (X/Ka)微波遥感系统研制升级为双线偏振双波段主被动微波遥感系统。对新系统及主要部件的工作原理、技术指标及研制改造方法作了介绍 ,还给出了一些初步的观测结果。
In order to enhance the sensing power of precipitating clouds, a dual polarization radar is developed to be added in an active and passive microwave dual wavelength (X/Ka band) remote sensing system. After this upgrading of dual polarization function, the advanced properties of the principle of the former remote sensing system are augmented. This upgraded system becomes a new capability of synthetical sensing clouds and precipitation, and will play an important role in precipitating cloud structure studies and all kinds of major science projects concerning obtaining quantitative distribution of clouds and precipitation, The working principle, the upgrading method and the specifications of the new system and its main components are given here. An emphasis is laid on the description of the design and implementing means of the antenna feeding unit, the control unit and data acquisition unit. A preliminary rainfall observation test of the system is also presented in this paper.
