Forest height is one of the influential information for managing forest cover and is also one of the criteria to evaluate the growth of organisms in the forest ecosystem. This paper suggests a novel coherence optimization algorithm to increase the accuracy of forest height estimation using the L-band PolInSAR images.

The paper proposed a novel threshold based algorithm of oil spill detection in the Synthetic Aperture Radar images. This threshold is a global one determined according to statistical analysis of pixel intensities of the images and their sizes. The simulation results of the proposed method on Python software were compared with other methods, and proved that the proposed method significantly improved accuracy.

Rice acreage estimation using Sentinel-1A dual polarised SAR data in Udham Singh Nagar (Uttarakhand)
Udham Singh Nagar is one of major rice producing area of Uttarakhand state, and it falls in Tarai region. The soils of the region are considered as most fertile land in India and aptly support rice production. Rice is a mainly grown in the rainy season which results in a limited number of cloud-free optical remote sensing images for estimation of rice acreage and its monitoring. Sentinel-1A is a European radar imaging satellite launched in 2014. Sentinel-1A satellite launched as a part of the European Union's Copernicus program which provide Synthetic aperture radar (SAR) data i.e.

The increased demand for higher resolution and detailed SAR imaging builds up a pressure on the processing power of the existing systems for real time or near real time processing. Exploitation of GPU processing power could suffice the increasing demands in processing. The processing of initial SAR systems was based on the principles of Fourier Optics.

This paper presents a methodology to determine inundation area in a flood event in Ha Tinh Province, Vietnam, by applying Synthetic Aperture Radar (SAR) image processing, in combination with Digital Elevation Model (DEM) for threshold detection. Sentinel-1 images were down loaded from an open source provided by European Space Agency (ESA). DEM data were collected from United States Geological Survey (USGS).

A synthetic aperture radar (SAR) is a radar sensor that provides azimuth resolution superior to that achievable with its real beam by synthesizing a long aperture using platform motion. The geometry for the production of the SAR image is shown in Fig. 33.1. The SAR is used to generate an electromagnetic map of the surface of the earth from an airborne or spaceborne platform. This electromagnetic map of the surface
