抄録

<p>This work presents a novel digital intermediate frequency (IF) module designed for hyperspectral microwave radiometers, enabling the detection of non-uniform channels. The IF module is based on polyphase filter bank and fast Fourier transform techniques, capable of processing sampling data from high-speed analog-to-digital converters (ADC) in real time. The module is implemented on a circuit board featuring a 6.4 gigabit samples per second sampling-rate ADC and Xilinx Vertex-7 field programmable gate array, followed by performance testing and analysis. When combined with an appropriate radio frequency front-end, this IF module can form a hyperspectral microwave radiometer with non-uniform channel detection capability, finding applications in various microwave remote sensing fields.</p>
