Multi-Temporal Speckle Filtering of Polarimetric P-Band SAR Data over Dense Tropical Forests: Study Case in French Guiana for the BIOMASS Mission

Airborne multi-temporal L-band polarimetric SAR data for biomass estimation in semi-arid forests

metrics for the detection of changed buildings in 3d old vector maps using als data (case study: isfahan city)

هدف از این تحقیق، ارزیابی و بهبود متریک های موجود جهت تایید صحت نقشه های قدیمی سه بعدی برداری با استفاده از ابر نقطه حاصل از لیزر اسکن جدید شهر اصفهان می باشد . بنابراین ابر نقطه حاصل از لیزر اسکنر با چگالی حدودا سه نقطه در هر متر مربع جهت شناسایی عوارض تغییر کرده در نقشه های قدیمی سه بعدی استفاده شده است. تمرکز ما در این تحقیق بر روی ساختمان به عنوان یکی از اصلی ترین عارضه های شهری می باشد. من...

Estimating Forest Biomass in Temperate Forests Using Airborne Multi-frequency Polarimetric SAR Data

We used multi-sensor, multi-frequency and multi-polarization SAR data for biophysical parameter retrieval in plantation forests of Northern Japan. The statistical relationships with different biophysical parameters are quite robust for certain frequencies-polarization combination. A combination of different frequencies and polarizations facilitate the retrieval of these parameters with R of 0.9...

Clustering of Multi-temporal Fully Polarimetric L-band Sar Data for Agricultural Land Cover Mapping

Recently, the unique capabilities of Polarimetric Synthetic Aperture Radar (PolSAR) sensors make them an important and efficient tool for natural resources and environmental applications, such as land cover and crop classification. The aim of this paper is to classify multi-temporal full polarimetric SAR data using kernel-based fuzzy C-means clustering method, over an agricultural region. This ...

A Hybrid Model for Interferometric and Polarimetric P-band Sar Imaging of Forests

In this paper, a forward model for extended covariance matrix prediction for boreal and hemi-boreal forest in Pband SAR is presented. The main product is the extended covariance matrix scaled to sigma nought on the diagonal. The input parameters consist of basic radar setup, topography, forest biome, biomass, and some model parameters. Backscatter intensities for HH, VV, and HV channels are pre...
