摘　　要：阐述HFDL信号有着广泛应用,所以在信号探测中对其进行筛除可有效减少冗余信息。针对宽频带中HFDL信号频率估计与检测难题,采取以标准频谱模板对宽带待检信号进行相关匹配的方法。该算法通过对比信号频谱的相关性,能够实现对HFDL信号频点的粗估计与识别,并通过对比试验,验证算法的有效性。This paper describes that because HFDL signals have a wide range of applications,filtering them out in signal detection can effectively reduce redundant information.To address the challenge of HFDL signal frequency estimation and detection in broadband,a method using standard spectral templates for correlation matching with the broadband signals under test has been adopted.This algorithm can achieve a rough estimation and identification of HFDL signal.Through comparative experiments,the effectiveness of the algorithm has been verified.
