摘要
相位解缠绕(Phase Unwrapping,PU)是干涉合成孔径雷达(Synthetic Aperture Radar Interfering,In SAR)中的关键步骤。单基线相位解缠绕(Single-baseline PU,SB-PU)因受相位连续性假设的限制,无法求解复杂地形,而不受相位连续性假设限制的多基线相位解缠绕(multi-baseline PU,MB-PU)却普遍存在噪声鲁棒性差的缺点。本文从PU模型出发,分析了它们的优势与缺陷,阐述了将基于Lp-norm的SB-PU求解架构引入MB-PU方法的思想与模型,并探讨了未来可开展的研究工作。
Phase unwrapping(PU)is a crucial step in synthetic aperture radar Interfering.Single-baseline PU(SB-PU)is unable to meet the actual demand of solving complex terrain due to phase continuity assumption.Although multi-baseline PU(MB-PU)can overcome the limitation of phase continuity assumption,generally have the drawback of poor noise robustness.Based on the mathematical model of SB and MB-PU,this paper analyzes their advantages and disadvantages from the perspective of the model.The idea,method and mathematic model of combine the SB-PU solver framework with MB-PU methods are described in detail,and the possible future work be discusses further.
