摘　　要：提出了一种短波莫尔斯(Morse)信号电台属性的自动判证方法,该方法通过联合时域幅度、频域带宽等信息,实现莫尔斯信号点、划长度等特征高精度测量,结合改进K近邻算法,实现莫尔斯信号电台属性的自动判证。结果证明,该算法结构简单,处理性能优,能够在不做码表映射的情况下判别电台属性。In this paper,an automatic attribute determination method for short wave Mores signal radio station is proposed,Which realizes the high-precision measurement of Mores signal features such as point and stroke length by combining the information of time domain amplitude,time domain phase and frequency domain bandwidth,and realizes the automatic attribute determination of Morse signal radio station by combining with the improved k-nearest neighbor algorithm.Theresule show that the algorithm has simple structure and good processing performance,and it can distinguish the attributes of radio stations without code table mapping.
