Keyword亚马逊热带雨林 星载sar 双程天线方向图 辐射校正 波束指向监测
Abstract利用亚马逊热带雨林后向散射系数的稳定性可获取星载合成孔径雷达(SAR)俯仰向双程天线方向图并对SAR图像进行辐射校正.给出了基于亚马逊热带雨林星载SAR数据实现天线方向图的估值方法,并利用绝对校正后的SAR图像散射系数沿距离向的衰落特性获得了在轨天线波束指向偏差的估计.仿真结果表明了利用本文算法基于亚马逊热带雨林星载SAR数据获取俯仰向天线方向图的可靠性和稳定性.
Other AbstractAmazon tropical rain fo rest, due to the constant back scat tering coeff icient, is w idely u sed for spacebo rne SAR ( Syn thet ic Apertu re Radar)range pat tern measu rement and the radiometric calib ration of sapcebo rne SAR images.Based on the data of Amazon t rop ical rain fo rest,the parameter est imat ion methods of spacebo rne SAR pat tern model are provided,and the shaped pat tern est imat ion is discu ssed. A f ter the ab so lu te radiomet ric calib rat ion of SAR image is perfo rmed,the detection of beam point ing error acco rding to the decline of back scat tering coeff icien t of the calib rated SAR image along the range is discu ssed. The simu lated resu lt s indicate the reliability and stability of the proposed algo rithms.
