摘　　要：基于现场可编程门阵列(FPGA)可重构技术,设计了一种具有资源共享、可灵活重构特征的信号检测系统。基于MicroBlaze设计了重构控制模块用于控制FPGA内的局部动态重构。利用可重构的数字滤波器对采样信号进行滤波,提高FPGA器件的硬件资源利用率。采用幅度自相关累加技术提高信号检测准确率,同时信号检测模块可以选择不同的自相关累加数进行重构。设计的可重构信号检测系统能够满足不同的信号检测需求。Based on field programmable gate array(FPGA)reconfigurable technology,a signal detection system with resource sharing and flexible reconfiguration is designed.A reconfiguration control module based on MicroBlaze is designed for controlling the local dynamic reconfiguration in FPGA.The reconfigurable digital filter is used to filter the sampled signals for improving the hardware resource utilization of the FPGA device.The amplitude autocorrelation accumulation technology is used to improve the accuracy of signal detection,and the signal detection module can be reconfigured with different autocorrelation accumulators.The designed reconfigurable signal detection system can meet different signal detection requirements.
