摘　　要：深入分析了莫尔斯信号的时域频域特性和短波宽带信号识别的难点,给出了自动识别算法的理论基础,并在此基础上利用宽带快速搜索和窄带精确识别相结合的方法进行了算法设计和工程实现设计,最后给出了算法的实测结果。试验结果表明,对天线接收的实际短波莫尔斯信号具有很高的侦察识别正确率和比较低的虚警和漏警率。Based on the deep analysis of Morse signal＇s characteristics and the di^culty of signal identification in shortwave wideband channel, a new identification method is put forward by combining fast signal search in wideband and exact analysis in narrowband in shortwave channel, and based on it, an implemental method on engineering is designed. The experiment resttlt indicates that this method has very high identification probability and low false alarm and leak alarm probability for real shortwave Morse signal received by antenna.
