| 摘 要： | 海浪有效波高与雷达的海杂波强度有关,但是无法直接由雷达图像得到.借鉴运用SAR图像计算有效波高的方法,即假设有效波高与雷达回波强度信噪比的平方根成线性关系,可以由X波段雷达图像计算得到海浪的有效波高.将在小麦岛和南海分别进行的岸基试验和船基试验获得的浮标资料和雷达资料结合起来分析,结果表明用X波段航海雷达测量有效波高的最大误差不超过9%. |
| 关 键 词： | X波段雷达 有效波高 海杂波图像谱 海浪谱 |

| Abstract: | The significant wave height is related to the intensity of the sea clutter,but can not be derived directly from radar images.Applying the method to calculate the significant wave height from the SAR imagery,which supposes the significant wave height in linear relation with the square of the signal-to-noise ratio of radar images,the significant wave height can be estimated from the images of X-band radar.Analyzing the buoy information of shore-based and ship-based experiments separately performed in the Smal... |
| Keywords: | X-band radar significant wave height wave number spectrum image spectrum of radar images |
