radarsat meaning in Chinese
加拿大卫星
雷达卫星
Examples
- After the introduction of the wavelet theory and the principle of wavelet - based image fusion , we test the radarsat and landsat images using gray - value algorithm
在对小波变换的基本理论和其用于融合的原理进行介绍之后，我们利用了灰度值选择算子针对radarsat和landsat图像进行了相关实验。 - Based on the method described above , experiments are taken on multitemporal radarsat images . we obtain satisfactory results and validate the availability of this method on sar image registration
采用上述方法，本文对不同时段、不同季节拍摄的sar图像进行了实验，获得了较满意的配准结果，验证了本方法对sar图像的适用性。 - When it comes to feature - based image fusion , we make use of mean - shift to extract appropriate features according to the characteristics of radarsat and landsat images , then apply the bayes theory to feature level fusion classification
在特征级的图像融合中，我们针对radarsat和landsat图像的特点，采用滑动窗方法提取适当的特征，然后用bayes理论来进行特征层的融合分类。 - In this study , we demonstrate a technique using the multi - temporal c band hh polarized radarsat scansar data to estimate the relative soil moisture change . the experiment data from sgp97 covered a whole range of vegetation growing season and different type agriculture fields
研究证明，星载合成孔径雷达( sar )得到的地表后向散射系数与地表介电常数有直接相关关系，从而能够在水文模型要求的精度范围内有效提取地表土壤水分信息。 - The currently available satellites , however , are single polarization , single frequency sensors such as ers - 1 / 2 , radarsat , and jers - 1 . there is a need to develop a technique to estimate soil moisture information from these available data sources at both regional and local scales
传统的测量方法，如重量法测量和时域反射计都是基于点的测量方法，需要实地操作和烦杂的后处理过程，而且无法在要求的时间精度范围内得到地表土壤水分的空间分布信息。
