Abstract

The invention relates to a wave measurement radar based on a continuous wave, and aims to solve the technical problem of low automation degree. The wave measurement radar comprises: a transmitting antenna, a receiving antenna, an excitation source, a signal generating unit, a band-pass filter, a receiver unit, a signal processing unit, a data processing unit, a communication module, and a power module. The wave measurement radar is mounted in a height of 0.5 to 60 meters from the water surface, and the antenna is vertically downward or at a certain angle to the lower water surface. The signalgenerating unit and the signal processing unit comprise a signal generator that generates a fixed frequency continuous wave, a frequency modulated continuous wave, and a step frequency modulated continuous wave signal, and perform sampling and preprocessing according to the signal form. The data processing unit calculates a preprocessing result to obtain a wave height, a wave period, and a tide level. According to the wave measurement radar based on the continuous wave, the problem is solved.

Description

technical field [0001] The invention relates to the field of wave measuring radar, in particular to a wave measuring radar based on continuous waves. Background technique [0002] Ocean waves are the most common and important ocean fluctuation phenomenon, which are closely related to many important issues such as ocean exploration, ocean development and utilization, as well as marine military technology and maritime navigation safety. In the design and construction of harbor projects, offshore wind power projects, hydraulic projects, etc., the design value of wave elements is one of the most basic and important hydrological elements. The particularly large wind and wave elements have a great influence on the loads of marine engineering and water conservancy structures, and have a significant impact on the accuracy of wind power forecasting. The analysis content of wave spectrum is listed in my country's marine survey specifications and coastal observation specifications, wi...
