摘要: |
侧音测距系统的最大无模糊距离受到侧音信号最低频率的限制.为此,分析了产生低频侧音的难点,以及使用低频侧音所带来的互相干扰、带宽增大、设备量增加等问题,提出了具体的解决方法,有效地提高了侧音测距系统的最大无模糊距离. |

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. |
