| Abstract: | Based on a single hydrophone in dipole sound field a positioning algorithm is presented, and the signal processing flow and Hough transform for hyperbola distilling are designed. It's proved by sea trials that the signal processing flow and hyperbola distilling have high processing gain, while the positioning algorithm is robust and accurate. This algorithm only needs simple equipments and is distinctive in radiating noise measurement and in parameter estimation of moving targets in short distance. |
| Keywords: | Dipole Short distance Parameter estimation of moving targets Hough Transform Hyperbola |
