With the availability of a huge number of polarization measurements, several semi-empirical BPDF models have been proposed. However, these models do not\u0000 pay much attention to canopy structure, which is fundamental for generation of polarization. In this article, we propose a new BPDF model using canopy structure information, which is parameterized by visible-sunlit areas. It is evaluated over grassland using POLDER BPDF and MODIS leaf area\u0000 index data sets. Experiments suggest that compared to Nadal–Bréon and Litvinov models, the new BPDF model reduces root-mean-square error by 7% and 10%, respectively. The new BPDF model also provides better performance when it is fitted using observations clustered by sun zenith\u0000 angle. The new BPDF model thus provides an effective tool for the study of land surface polarization.","PeriodicalId":49702,"journal":{"name":"Photogrammetric Engineering and Remote Sensing","volume":"86 1","pages":"745-752"},"PeriodicalIF":1.3,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49670029","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current simulations only consider single Rayleigh scattering of water molecules and ignore multiple Mie scattering of suspended particles. In this study, a method based on a combination of Monte Carlo\u0000 numerical simulation and Mie scattering theory is used to establish a model of the turbid underwater polarization distribution. Stokes vector and Mueller matrix are used to simulate the underwater polarization patterns within Snell's window. The distribution patterns and dynamic changes of\u0000 the simulation are consistent with field measurements. The maximum depth that the polarization pattern can be maintained is calculated for different water types. The influence of water turbidity on polarization patterns is discussed.

Since all the polarization information is modulated into an interferogram, demodulation becomes an\u0000 essential step. As the resolution of the obtained image continuously increases, the data to be calculated also increase. Therefore, a higher speed for the demodulation process is requisite. This article proposes a local filtering method and bypasses the frequency centralization method in the\u0000 frequency domain to improve the speed of demodulation. The demodulation time of an interferogram of size 1024×1024 pixels was reduced from 3.027 473 s to 0.134 637 s, increasing the speed of demodulation by 97.72%.
