Abstract: The development of underwater security systems is an important topic due to recent events. One approach to implementation is the use of passive SONAR systems, as this allows targets to be detected unnoticed. The use of distributed sensor systems is ideal for improved target detection. By adding further subsystems (nodes), it is possible to achieve more precise detection. In this context, so-called “ad-hoc systems” are being investigated, with which an arbitrary distribution of passive, static sensor nodes under water can be realized. Precise localization is made possible by knowing the position (and orientation) of the individual sensor nodes and suitable signal processing. In addition, all sensor systems include activity detection to reduce the error detection rate. This article presents the algorithms used for object and activity detection. Finally, the algorithms are tested in a simulation environment and the results are presented.
