NettetFirst, this paper summarizes existing underwater positioning technologies and methods of unmanned submersibles. According to the principle, underwater positioning methods are divided into four categories: inertial navigation, optics, acoustics, and other methods, and the advantages and disadvantages of the various positioning methods are analyzed. NettetBy utilising the microwave guided-mode propagation characteristics, we have proposed a new inspection method for underground FRPM pipelines. In our previous study, we confirmed that well-confined TE guided-modes (TE 0n ) can be easily excited in the frequency range of 2–6 GHz by use of standard line antennas (e.g. dipole/monopole) …
