    • The invention relates to a method of classifying one or several watercraft using the sound waves emitted or transmitted by these vehicles. The sound waves are thereby received using an array of underwater sound sensors of a sonar receiving system and processed into received signals. At least one amplitude spectrum is generated from these received signals consisting of one or more sets of frequency lines and any individual lines, from which the characteristic vehicle parameters are automatically determined in a frequency line pattern detection module or determined manually. Subsequently, the vehicle characteristic parameters are compared with the database parameters, where this comparison is evaluated with a matching factor. Considering the matching factor, one or several watercraft are determined as the result of the classification. In addition, the invention relates to a corresponding device for carrying out the process.
    • 本发明涉及一种使用这些车辆发射或发射的声波对一个或几个船舶进行分类的方法。 从而使用声纳接收系统的水下声音传感器阵列接收声波并将其处理成接收信号。 从由一组或多组频率线和任何单独的线组成的这些接收信号中产生至少一个振幅频谱,在频率线图案检测模块中自动确定特征车辆参数或手动确定特征车辆参数。 随后,将车辆特征参数与数据库参数进行比较,其中该比较用匹配因子进行评估。 考虑到匹配因子,作为分类的结果确定一个或几个船舶。 此外,本发明涉及用于执行该过程的相应装置。
