中文摘要 | 全极化微波辐射计的核心部分是复相关器。介绍了一种加法型模拟复相关器,它采用混合耦合器构成移相网络,在中频将电磁波信号相位调整到特定状态,从而实现了用加法思想获取全部Stokes参量。分别研制了分布参数和集总参数的移相网络,对它们测量并进行比较。最后对加法型模拟复相关器进行了整体测试,给出了噪声源测量下的相位反演能力测试。结果表明加法型模拟复相关器具有较好的极化测量性能。 |
英文摘要 | Fully polarimetric radiometers key component is the complex correlator.An additive analog complex correlator is represented in this paper.The phase-shifting network constituted by hybrid coupler is used to adjust the electromagnetic phase to a specific state in IF,and all Stokes parameters are obtained by using the additive thought.Both distributed and lumped parameters of phase-shift networks are developed respectively,their measurement and comparison are performed too.At last,the overall test for the additive analog complex correlator is presented,and the ability of the phase inversion under the condition of noise source measurement is discussed.The performed and results show that the additive analog complex correlator has a good performance in polarization measurement |
