The invention relates to the technical field of signal recognition, and discloses a ship automatic recognition method with selectable unidirectional and bidirectional functions, which comprises the following steps: receiving a radio frequency signal by using an antenna unit, and carrying out noise reduction anti-interference processing on the radio frequency signal by using a signal noise reduction algorithm to obtain a noise-reduced radio frequency signal; sending the radio frequency signal after noise reduction to the data processing unit; carrying out A/D sampling processing on the radio frequency signal after noise reduction by the data processing unit, and carrying out abnormal value processing on the AIS data after sampling; performing compression processing on the AIS data after abnormal value processing by using an AIS data compression algorithm, and performing driving track extraction on the compressed AIS data; and displaying the traveling track of the target ship on a display control unit, and judging the traveling distance with the target ship in real time. The invention also provides a marine automatic recognition instrument with selectable unidirectional and bidirectional functions. According to the invention, communication recognition of marine signals is realized.

    本发明涉及一种信号识别的技术领域,公开了一种单双向功能可选择的船用自动识别方法,包括:利用天线单元接收射频信号,并利用信号降噪算法对射频信号进行降噪抗干扰处理,得到降噪后的射频信号,并将降噪后的射频信号发送到数据处理单元;数据处理单元对降噪后的射频信号进行A/D采样处理,并对采样后的AIS数据进行异常值处理;利用AIS数据压缩算法对异常值处理后的AIS数据进行压缩处理,对压缩后的AIS数据进行行驶轨迹提取;将目标船舶的行驶轨迹显示在显控单元,并实时判断与目标船舶航行距离。本发明还提供了一种单双向功能可选择的船用自动识别仪。本发明实现了船用信号的通信识别。
