Test and Analysis of a Hyperspectral Microwave Radiometer Intermediate Frequency Module
IGARSS 2020-2020 IEEE International Geoscience and Remote Sensing …, 2020•ieeexplore.ieee.org
In this work, an IF (intermediate frequency) module of a hyperspectral microwave radiometer
is introduced. The IF module is designed with a 5GSPS sampling-rate ADC and a Virtex-7
FPGA. The module can achieve 512 channels and process all the sampled data in real-time.
The test results of this module are given and analyzed, such as linearity, sensitivity, etc. It
can be used in various applications of microwave remote sensing.
