“HY-1”卫星COCTS水色遥感器精确瑞利散射算法研究
Study of exact Rayleigh scattering arithmetic for COCTS sensor on “HY-1” satellite
-
摘要: “HY-1”卫星是我国自主研制发射的第一颗海洋卫星,水色遥感器COCTS具有8个可见光(412,443,490,520,565,670 nm)、近红外通道(750,865 nm)以及2个热红外通道(10.30~11.40,11.40~12.50μm).COCTS遥感器上采用了多元并扫技术用以提高遥感器的信噪比和探测灵敏度,但是由于并扫会带来像元旋转的问题,于是我国“HY-1”卫星水色遥感器COCTS上采用了K镜消旋技术,而K镜消旋技术带来的一个消极影响是偏振响应很大,通过发射前实验室监测结果发现其值达到了8%.
