一种微波雷达波浪水位测量装置

Microwave radar wave water level measurement device

Abstract

本实用新型涉及一种微波雷达波浪水位测量装置,微波发射器通过天线发射可连续调频的发射微波信号,并通过天线接收发射微波信号遇到待测水面返回的反射微波信号;反射微波信号与发射微波信号混频生成低频信号;数据处理器采集低频信号并输出水位测量装置至待测水面的距离。本实用新型采用连续调频波测距原理测量水面起伏程度,进而得到对应的水位(潮位)、波浪特征值等参数。本实用新型采用非接触式微波测距,不接触海水,可以用于海上恶劣、复杂多变的环境,准确、安全、稳定、不需要经常维护;可以实现自动高精度测量。
The utility model relates to a microwave radar wave water level measurement device, microwave emitter is through day line emission transmitting microwave signal of frequency modulation in succession to it meets the reflection microwave signal that the surface of water that awaits measuring returned to receive the transmitting microwave signal through the antenna, the reflection microwave signal generates low frequency?signals with the transmitting microwave signal mixing, data processor gathers low frequency?signals and exports the distance of water level measurement device to the surface of water that awaits measuring. The utility model discloses a frequency modulation ripples distance measuring principle measures surface of water undulation degree in succession, and then obtains corresponding water level (tidal level), wave characteristics isoparametric. The utility model discloses a non -contact microwave distance measurement, the contactless sea water can be used for marine environment abominable, complicated and changeable, accuracy, safety, stability, does not need the constant maintenance, can realize automatic high?precision?measurement.
