摘要
HY-1B卫星是中国第二颗海洋遥感卫星,水色水温扫描仪(COCTS)是其主要载荷。文章针对COCTS图像条带噪声的特点,采用傅里叶变换方法,设计了一种新的滤波器,对图像进行条带噪声去除,并同传统的低通滤波方法处理结果进行比较。实验结果表明,新的傅里叶变换方法能够有效地去除图像的条带噪声,其去除效果要优于传统的低通滤波方法。
Chinese Ocean Color and Temperature Scanner（COCTS）is the main payload on HY-1B satellite which is Chinese second ocean remote sensing satellite. A new filter in Fourier transform is used to destripe the noise of COCTS image,according to the characteristics of COCOT images. The destriped image is compared with traditional low-pass filter method. The result shows that the new Fourier transform method can effectively destripe image noise, and its destriping effect is higher than that of the traditional low-pass filter method.
