| 摘 要： | 本文介绍在《超短波通信电路设计手册》的基础上，如何考虑设计中的抗干扰措施，这些措施包括：从抗干扰要求出发，调配系统方程参数；选择合适的工作频率；选择有利于抗干扰的设备技术指标；发挥天线的抗干扰作用。在通信电路设计中采取的抗干扰措施，和改善设备的抗干扰措施，是水文遥测系统抗干扰的两个重要方面，缺一不可，系统设计者应该引起充分注意。

| Abstract: | This paper introduces some anti-interference methods to be taken in communication design for hydrologic telemetering system according to VHF/UHF Telecommunication Circuit Design Manual, which include parameters adjusting for the system equation, selection of proper working frequency, selection of equipment parameters appropriate for anti-interference, making full use of the antenna's anti-interference function. In design of telecommunication circuit of hydrologic telemetering system, it is important to take anti-interference measures and improve the equipment function in anti-interference, which should be paid attention to. |
