| Abstract: | Transponder is widely used in the underwater positioning and navigation system. It is more reliable and effective compared with other methods. This paper is based on the short baseline positioning system. It has been studied how to use the TMS320VC5509A as the core to design a transponder.The operational frequency of the transponder which we designed is in a wide range. A trial is conducted and confirmed that the device can operate a long time enough continuously and steadily within a certain range.The results are in line with the requirements. |
