| A Method for Increasing the Unambiguous Distance of Tone Ranging Systems |
|
| () |
| Abstract: |
| The unambiguous distance of tone ranging system is limited by the lowest frequency of tone. This paper analyses the difficulty in generation of low frequency signals, and gives a method by which low frequency signals can be generated easily. At the same time, techniques are provided to deal with problems resulted from application of low frequency side - stone. With this method, the unambiguous distance of tone ranging system can be increased effectively. |
