基于最大相关处理的跳频信号联合检测FPGA实现

FPGA Implementation of FH Signal Combining Detection Based on Most Correlation Process

文中对跳频信号检测中的最大相关处理法进行了改进,给出了基于最大相关处理的跳频信号联合检测方法。该方法利用跳频周期这一先验信息对最大相关处理后的结果进行分析,进一步判定是否存在跳频信号。相对于最大相关处理法,该方法降低了信号检测的虚警概率,提高了检测的准确性。文中对该方法的实现方案进行了介绍,并且使用VHDL描述了方案中的各个模块,最后在QuartusII下进行了综合、仿真,证明了其有效性。

This paper describes the improvement on most correlation process method, a FH signal detection method, and presents a FH signal combined detection method based on most correlation process. This method uses FH signal period, the apriori information, and analyzes the result of most correlation process, thus to determine the existence of FH signal. It reduces false alarm probability and raises the accuracy of signal detection as compared with most correlation process methods. This paper discusses the implementation scheme of this method, describes the modules of the scheme by using VHDL, makes its synthesis and simulation and thus testifies its efficiency in Quartus Ⅱ.
