Study on wave measurement based on RTK technology and spectral estimation

The traditional methods of wave measurement usually adopt various sensors to realize the collection of the field wave data, which are limited by the working life of the sensors and their performance; and their ability of anti-interference is relatively weak on site. Therefore, this paper presents a new method for wave measurement. In this paper, by taking advantage of the Beidou Satellite Navigation System (BDS) and RTK technology, the single point on the sea surface is accurately located, and the three-dimensional coordinates of the point are obtained; after getting the height change sequence of the water surface, the wave parameters are obtained by the spectral estimation. The experimental results show that this method can not only measure the wave data accurately, but also has the characteristics of simple system, low cost and strong anti - interference ability.
