摘要：

The Matched correlation filter based on FPGA is designed for quasi real-time processing of impact acceleration signal in this paper. The design integrates match-filtering algorithm with correlation algorithm, proposing matched correlation algorithm. According to this algorithm, the design uses two Radix-4 FFT modules to complete the correlation operations, using single sine wave as matching model signal which has better correlation with impact acceleration signal. Furthermore, a re-sampling module and data integration module are added for the stability and reliability of signal processing. The filter was simulated and demonstrated by Modelsim for its good quasi real-time processing and reliability.
