摘要： The invention relates to a method for determining a frequency line pattern within at least one amplitude spectrum that is produced from audible signals that have been radiated by at least one detected vehicle and received by means of a sonar installation. First of all, a predetermined number of frequency lines in the or each amplitude spectrum are selected and are sorted in order of decreasing amplitude magnitude and are selected using a threshold value that ensures that a predetermined suitable number is not exceeded. Following stipulation of a plurality of threshold values, frequency lines that have been selected taking account of at least one threshold value are compared with one another. The line pairs formed by the comparison are used to determine preliminary frequency line sets with an associated fundamental frequency that are rated on the basis of their identifiable structures. An exclusion method is used to form the final frequency line sets, taking account of a rating that is dependent on the sequence, the number, the density, the amplitude and the fundamental frequency of the frequency lines. It is then possible to find strong single lines that the spectrum may contain. For each detected vehicle, it is therefore possible to assign a target-oriented frequency line pattern that can be used to classify the vehicle. The invention also relates to an appropriate apparatus for carrying out the method according to the invention.

摘要： The invention relates to a method for separating a collection of ships and to a group of ships, in particularly a group of military ships. Said group of ships comprises at least two watercrafts (301, 303) and the watercrafts emit underwater sound waves. Said method also enables individual ships to be detected.

摘要： The invention relates to a method for classifying one or more watercraft on the basis of the sound waves (2) emitted or transmitted by these craft. In this case, the sound waves (2) are received by an arrangement of waterborne sound sensors of a Sonar receiving installation (4) and processed to form received signals (6). At least one amplitude spectrum (24) is produced from these received signals (6), said amplitude spectrum (24) having one or more sets of frequency lines and possible single lines, from which characteristic craft parameters (28) are determined automatically in a frequency line pattern identification module (26) or manually. Subsequently, the characteristic craft parameters (28) are compared with parameters in a database, with this comparison being rated with a correspondence factor (34). One or more watercraft are determined as a result of the classification, taking the correspondence factor (34) into account. Furthermore, the invention relates to a corresponding device for carrying out the method.
摘要翻译： 本发明涉及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。 因此，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，从而可以在频率线图形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，将车辆特性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多个船舶。 此外，本发明涉及一种用于执行该过程的相应装置。
