Abstract


The radar signal processing integrated application of digital signal processing , the computer , the ultra-large-scale integration (VLSI) and digital circuit technology . With the wide application of field programmable gate array (FPGA) , so that has an important position in the radar signal processing based on FPGA implementations of digital signal processing . FPGA 's small size , speed , stability , etc. are superior DSP using FPGA implementation will be an inevitable development trend of the radar signal processing . Meanwhile , the FPGA processes the finite wordlength effects is extremely important. According to the basic principles of radar signal processing , combined with current research -based FPGA signal processing capabilities , radar signal processing FPGA , and a detailed analysis of the finite word-length effects processing . This article first gave a brief description of finite word-length effect , on this basis , the FPGA implementation of radar signal processing and error are briefly described . Followed by the implementation of the principle of the direct digital frequency synthesis (DDS) and its FPGA is described in detail , and a detailed analysis of the DDS spurious . Then introduced the principle of pulse compression and its FPGA implementation , and analysis of the errors . Finally , the discussion of the principles of the FIR filter and its effective wordlength effects .
