What does the acronym VDS stand for in mine detection technology?

The acronym VDS stands for Variable Depth Sonar in mine detection technology. This technology involves the use of sonar systems that can operate at various depths in the water column, allowing for effective detection of underwater mines or objects. The ability to adjust the depth enhances the system's capability to detect mines located at different levels, providing a more comprehensive search and improving the accuracy of the detection process. By varying the depth of the sonar scans, this approach can also optimize the detection rates depending on the specific underwater environment and conditions, making it a crucial tool in maritime mine countermeasures.
