Abstract:
For hyperspectral microwave radiometer, its intermediate frequency (IF) module need to divide the signal into thousands of channels. The ADC output of the IF module will up to dozens of GSPS. In order to process such huge data in real time, the FPGA of IF module needs to spend a lot of resources and energy to process the data in parallel, which limited the development of hyperspectral microwave radiometer. In this paper, a method to reduce the FPGA resource consumption for IF module of hyperspectral microwave radiometer is proposed. Using the relationship between odd and even sequences of real signals and complex FFT core, the utilization rate of FPGA resources is improved and the resource consumption of IF module is reduced effectively. The theories, resource consumption analyze, and test results are shown in this paper, which verified that this method can be applied to the optimize the IF Module of hyperspectral microwave radiometer very well.
