FPGA processing technology on impact signal

Abstract

The paper chooses the penetration impact signal as the research object. The matched filtering algorithm has been used to process the impact signal according to its frequency. On the analysis of the correlation algorithm and radix-4 FFT algorithm, the paper puts forward an implementation algorithm on FPGA of the fixed geometric structure addressing. By using fixed geometry addressing, pipeline design and block floating point structure, the data has the greater precision and dynamic range. The results show that the design is efficient, strong extensive and occupies less resource. It is an effective method to meet the high-speed digital signal processing requirements.
