Pandangan berbilang suai ialah langkah pemprosesan kritikal dalam pengukuran radar bukaan sintetik interferometrik berbilang temporal (InSAR), terutamanya dalam subset garis dasar temporal yang kecil. Pelbagai pendekatan multilook adaptif berasaskan amplitud telah dicadangkan untuk penambahbaikan pemprosesan interferometrik. Walau bagaimanapun, isyarat fasa, yang merupakan asas dalam sistem interferometrik, biasanya diabaikan dalam kaedah ini. Untuk mengeksploitasi sepenuhnya maklumat dalam imej SAR kompleks, multilooking adaptif bukan tempatan dicadangkan berdasarkan matriks kovarians kompleks dalam kerja ini. Isyarat kompleks di sini dieksploitasi untuk pengukuran persamaan antara dua piksel. Memandangkan kerumitan objek dalam imej SAR, pengesanan ciri struktur diperkenalkan untuk menganggarkan matriks kovarians secara adaptif. Keberkesanan dan kebolehpercayaan pendekatan yang dicadangkan ditunjukkan dengan eksperimen ke atas data simulasi dan sebenar.

Abstract: Adaptive multilooking is a critical processing step in multi-temporal interferometric synthetic aperture radar (InSAR) measurement, especially in small temporal baseline subsets. Various amplitude-based adaptive multilook approaches have been proposed for the improvement of interferometric processing. However, the phase signal, which is fundamental in interferometric systems, is typically ignored in these methods. To fully exploit the information in complex SAR images, a nonlocal adaptive multilooking is proposed based on complex covariance matrix in this work. The complex signal is here exploited for the similiarity measurement between two pixels. Given the complexity of objects in SAR images, structure feature detection is introduced to adaptively estimate covariance matrix. The effectiveness and reliability of the proposed approach are demonstrated with experiments both on simulated and real data.
