FR4.L10.3: HOW DOES DEW AFFECT L-BAND BACKSCATTER? ANALYSIS OF PALS DATA AT T...grssieee
1. The document analyzes how dew affects L-band backscatter using data from an Iowa field site, which has implications for NASA's upcoming SMAP mission.
2. Dew was found to increase L-band backscatter from a soybean field by up to 1.3 dB, with the greatest effect on direct canopy backscatter.
3. The presence of dew may cause incorrect soil moisture estimates from SMAP if backscatter changes sub-daily due to changing canopy water from dew.
FR4.L10.2: A MICROWAVE SCATTERING MODEL OF VEGETATED SURFACES BASED ON BOR/DD...grssieee
This document describes a microwave scattering model for vegetated surfaces being developed for NASA's Soil Moisture Active Passive (SMAP) mission. The model uses numerical solutions of Maxwell's equations to simulate scattering from both rough soil surfaces and vegetation volumes. It represents surfaces and vegetation as 3D "data cubes" that allow fast interpolation. Comparison to experimental data from a grassland site shows good agreement between modeled and measured backscatter values. The model will be used to retrieve soil moisture from SMAP radar measurements by inverting the physical scattering model.
The document discusses applications of the integral equation model (IEM) in microwave remote sensing for retrieving land surface parameters. It presents the IEM and its advantages over traditional models. It then describes using IEM and AIEM simulations to develop parameterized emission models and inversion algorithms for retrieving soil moisture from satellites like AMSR-E and sensors like SMOS and SMAP. Validation results using experimental radiometer data show the algorithms can accurately estimate soil moisture.
TU1.L10 - ERS-ENVISAT TANDEM CROSS-INTERFEROMETRY FOR MONITORING OF SEA ICEgrssieee
The document discusses using cross-interferometry from ERS-ENVISAT tandem missions to monitor sea ice. It has very large baselines which allows it to be sensitive to small changes in height. It was used to monitor glaciers in Greenland and Antarctica, detecting ice movement between acquisitions only 30 minutes apart. Initial results over the Arctic show potential for monitoring sea ice dynamics, including estimating two-dimensional displacement vectors and detecting changes around the Northwest Passage in Canada between January 2004 acquisitions. Further data from the third campaign over Antarctica is also discussed.
A SEMANTIC-BASED MULTILEVEL APPROACH TO CHANGE DETECTION IN VERY HIGH GEOMETR...grssieee
This document proposes a general top-down approach for change detection in very high resolution multitemporal images. The approach models different types of radiometric changes, extracts semantic meaning from changes, and identifies changes of interest. It uses a multilevel architecture including pixel, primitive, and object levels to represent radiometric changes. The approach was tested on Quickbird images of Trento, Italy from 2004 and 2006, detecting changes more accurately than existing techniques.
The document discusses applying azimuth phase coding (APC) techniques to suppress range ambiguities in multichannel synthetic aperture radar (SAR) systems. It finds that while APC does not produce a simple Doppler shift in multichannel SAR signals as it does in conventional systems, it can still provide improved ambiguity suppression. The level of suppression depends on factors like the azimuth antenna pattern, oversampling ratio, and number of receive channels. When applied to example high-resolution wide-swath SAR systems, the reflector-based design achieved 3-8 dB of suppression compared to 0.7 dB for the planar design.
This document presents a new approach for classifying multispectral remote sensing images using weighted pixel statistics. The approach combines spectral signatures from images to perform accurate classification. Simulation results on synthesized test images show the approach provides more accurate classifications with fewer unclassified zones compared to traditional weighted order statistics methods, demonstrating the efficiency of the proposed approach. Future work is outlined to further evaluate performance.
The document presents a multi-frame marked point process model for extracting targets from ISAR (Inverse Synthetic Aperture Radar) image sequences. The model integrates information across frames using priors on target shape persistency and smooth motion. Experiments show the model achieves better target line and center extraction compared to frame-by-frame detection. Future work involves generalizing the model to identify other objects like airplanes and using extracted features for target classification.
Recent Advances in Object-based Change Detection.pdfgrssieee
This document summarizes recent advances in object-based change detection methods. It presents a new multiresolution segmentation approach adapted for change detection that segments images independently but checks for consistency between segments. Object correspondence is established through directed or intersected objects. Change detection is performed using IR-MAD. The methods were tested on aerial imagery and showed good overall accuracy rates above 98%, demonstrating the promise of object-based change detection techniques. Further developments are needed to improve consistency tests, segmentation parameter selection, and implementation.
This document proposes a new SAR superresolution imaging algorithm based on adaptive sidelobe reduction (ASR). It outlines issues with conventional weighting methods and describes how the new algorithm uses ASR to suppress sidelobes without degrading resolution. Simulation results show the new method improves resolution and lowers sidelobes compared to conventional Fourier techniques.
Tomographic Profiling (TP) is a new imaging scheme that provides vertical backscatter profiles through targets like snow, ice, vegetation and forestry from a single pass. TP retrieves a set of images at different incidence angles, with the incidence angle constant within each image. The document presents the TP technique, provides theoretical background, and shows experimental results from ground-based field and laboratory measurements using TP on forests, snowpacks, and laboratory targets. Future work includes an airborne demonstration of TP.
The document summarizes recent advances in analytical models for electromagnetic scattering from rough surfaces, including the statistical integral equation method (SIEM) and the extended advanced integral equation method (E-AIEM). SIEM incorporates surface slope statistics into the Kirchhoff approximation to improve accuracy. E-AIEM makes fewer assumptions than previous models and includes correction terms involving the error function for more accurate cross and complementary scattering coefficients, especially when surfaces or media are lossy. Testing shows these new methods agree well with full-wave simulations and experimental data.
This document summarizes an analysis of interference to spaceborne microwave radiometers operating in the 6-7 GHz band from downlinks of mobile satellite systems. It finds that interference exceeds acceptable levels in some cases, particularly when there is specular reflection off the ocean surface. The analysis is the first to quantify interference levels in ocean areas. Protection of the 6-7 GHz band for passive sensing is important but current radio regulations do not provide adequate protection.
This document presents a method for estimating the eigenvalues of a covariance matrix when there are few samples. It involves shifting the sampled eigenvalues toward the population values based on theoretical distributions, and balancing the energy across eigenvalues. This simple 3-matrix approach improves estimation and detection performance compared to using the sampled eigenvalues alone. Simulations and hyperspectral data experiments demonstrate the effectiveness of the method.
TerraHydro is a distributed hydrological system created by INPE to develop hydrographic basin applications using a graph structure to unify representation of water flow. It extracts local flows from different data structures and maps them to a single graph structure. This allows applications to be independent of the original data structure and makes operations over water flow formally defined. TerraHydro has functionality for extracting flow, redefining flow at different resolutions, calculating accumulation areas, and delineating basins and river reaches. It was developed using open source libraries TerraLib and TerraView.
Wavemill is a proposed ocean surface current measurement mission concept that uses hybrid interferometry. A feasibility study generated promising results showing potential accuracies better than 10cm/s. Risk reduction activities are underway, including an airborne demonstration campaign and development of an end-to-end simulator. The next steps include a product assessment study and advancing the instrument design and mission requirements.

The document discusses the transition of the NPOESS environmental monitoring program to two new programs - JPSS led by NOAA/NASA and DWSS led by the DoD. It outlines the status of the NPP satellite, ground systems, calibration/validation plans, and data readiness for users. The transition aims to ensure continuity of critical weather and climate observations through international collaboration between the US and European agencies.
