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.
