Optimal selection of interferometric SAR phase fringe image with residue

摘要: 該文基于相位展開中殘余點(diǎn)的概念，深入研究了殘余點(diǎn)發(fā)生概率與配準(zhǔn)精度間的內(nèi)在聯(lián)系，根據(jù)所得出的模型，提出以殘余點(diǎn)的數(shù)目作為衡量不同配準(zhǔn)結(jié)果的準(zhǔn)則，挑選出最佳的條紋圖，從而最大程度地減小數(shù)字高程圖中因配準(zhǔn)所引起的誤差。實(shí)際數(shù)據(jù)的研究表明，該方法簡便精確、行之有效。

Abstract: In this paper, the intrinsic relationship between registration accuracy and probability of residues referred to in phase unwrapping is investigated. Based on the derived model, it is presented that the number of residues can be used as a criterion to judge the registration results and select the optimal phase fringe image, which will reduce the error caused by misregistration as possible as much. The experiments show the effectiveness of this approach. -
