| Abstract | 以探测大气中水汽吸收谱线为应用背景，系统设计了一种基于快速傅里叶变换(FFT)的宽带宽的谱分析技术的微波辐射计。阐述了谱分析技术的微波辐射计的设计原理，详细介绍了系统结构设计、接收机方案设计和谱仪的方案设计，并分析了系统的主要技术指标、正交接收机指标及谱仪的设计。该系统可实现的辐射计探测频率为22.235 GHz，设计带宽达到500 MHz，谱分辨力为60 kHz。 |
| Other Abstract | A broadband Fast Fourier Transform(FFT) algorithm radiometer is designed in order to detect the absorption spectrum of the atmospheric water. The design principle of the radiometer, the system structural design, the project design of the receiver and the spectrometer are introduced in detail. The main technical indexes of the orthogonal receiver and spectrometer are analyzed. This system can be used to detect the frequency of 22.235 GHz, and its designed bandwidth can reach 500 MHz with the spectral resolution of 60 kHz. |
