摘要/Abstract

摘要： 为实现微波辐射计大带宽数字化探测的需求，解决现场可编程门阵列（Feild Programmable Gate Array，FPGA）内部处理速度限制输入数据速率的问题，提出了一种基于多相滤波器组和高级快速傅里叶变换（Fast Fourier Transform，FFT）结构的高速数字谱仪设计方案，介绍了多相滤波器组和高级FFT理论基础并给出了具体的硬件设计和硬件实现，完成了硬件的功能仿真，将MATLAB仿真和硬件功能仿真的结果进行对比，验证了该设计方案的可行性.在低时间成本和低经济成本条件下，该方案可实现微波辐射计后端的灵活配置和共享多个微波辐射计前端的功能.

Abstract: High speed data rate due to the improvement of frequency band of microwave radiometer gives a great challenge to design the backend of microwave radiometer. A method of a combination of polyphase filterbanks structure and advanced FFT structure was presented to solve this problem. This paper gave the design and key implementation of this method, compared result of mathematical method on MATLAB and that of implementation on FPGA. The results match each other well, which means that this method can work in designing high speed digital spectrometer. It is new in the design of backend of microwave radiometer used to achieve broadband measurement of atmosphere. It is flexible to change the design of backend to share different front ends of microwave radiometer at low time and financial cost. At the same time, it is a good resolution to realize high speed digital spectrometer.

Key words: high speed digital spectrometer, polyphase filterbanks, advanced FFT method, microwave radiometer
