| Abstract: |
| This paper introduces the universal digital signal processing platform of radar receiver,which requires miniaturization,universalization and real-time operation.A new FPGA product of Xilinx Inc,Spartan-3 series,is used to complete the FFT submodule and the processing speed and the precision can meet the requirement of the system.It's the base of the following analysis. |
| Key words: HF ground wave radar receiver signal processing platform design |
