X波段导航雷达浪高实时测量研究

针对舰船对浪高实时测量的需要,提出了基于X波段导航雷达浪高实时测量的方案。介绍X波段导航雷达浪高测量原理,建立基于X波段导航雷达浪高实时测量的数学模型。通过某海域实测采集的雷达图像,经过数学模型反演得出浪高实时数据,并与采用浮标传感器实时测量的浪高数据进行对比,发现X波段导航雷达与浮标传感器测得的浪高数据有近一致的线性关系,标准差也较小。从一定程度上为舰船浪高测量提供一种可行性方法。

Research on real-time wave height measurement using X-band navigation radar

In order to meet the warship's needs of real-time wave height measurement,a method using X-band navigation radar to measure wave height is presented.In this paper,the principle of wave height measurement based on X-band navigation radar is introduced,and a mathematical model of wave height measurement using X-band navigation radar is built. According to the X-band radar-image sequences collected from sea areas of China,the wave heights are retrieved based on the mathematical model.The retrieved wave heights are validated by comparison of the resulting radar-derived significant wave heights.With the significant wave heights acquired from in-situ buoy sensors,it is shown that the accuracy of the radar-retrieved significant wave height is consistent with the accuracy of the in-situ buoy sensors.Therefore,to some extent,the reliability of the mathematical model is verified,and the wave height measurement using X-band navigation radar is available in the warship.
