Efficient simulation of sar interferograms of large areas and of rugged terrain

IEEE Transactions on Geoscience and Remote Sensing, 2003
Interferometric synthetic aperture radar (InSAR) techniques are today applied in many areas of remote sensing, ranging from digital elevation model (DEM) generation to surface motion mapping and InSAR tomography. To enhance the understanding of the InSAR mapping process and to test new algorithms, accurate tools for the simulation of the topographic ...

Analysis of the Kernel-Driven Brdf Model Over Rugged Terrains

IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019
Land-surface bidirectional reflectance distribution function (BRDF) models are used for the description of surface bidirectional effects and the estimation of surface albedo. The semi-empirical linear kernel-driven BRDF model is one of them which has been adopted by the moderate resolution imaging spectroradiometer (MODIS) operational BRDF/Albedo ...

A contribution to the problem of spacing raingauges in rugged terrain

Journal of Hydrology, 1970
Abstract It is known that the ‘areal variability’ of rainfall is affected by the nature of the terrain, and that it is necessary to establish a greater network density in mountainous areas than in flat ones. The selection of raingauge density has usually been done by rule of thumb or by trial and error methods. This paper examines the possibility of

An accurate SAR co-registration method for rugged terrain

SPIE Proceedings, 2009
Accurate co-registration of synthetic aperture radar (SAR) images is essential for SAR interferometric applications such as along track interferometry (ATI) and across track interferometry (XTI). In this paper, we present a non-linear and linear joint algorithm for the SAR image co-registration which could be used in highly rugged terrain.

Atypical fire behaviours in rugged terrain

Bushfires are a frequent natural phenomenon in many parts of the world, which have both positive and negative impacts on the environment and human beings. Although these fires are important in cycling nutrients in soils and rejuvenate terrestrial biomes through promotion of regeneration in fire-tolerant plants, they are frequently catastrophic ...

Simple correction of multiple reflection effects in rugged terrain

International Journal of Remote Sensing, 2009
Operational correction of optical satellite sensor imagery usually models radiation reflected from surrounding terrain with a first-order reflection function. In rugged areas and snowy environments, the trapping of radiation between adjacent slopes can make such an approximation inadequate, leading to underestimation of the amount of irradiance, and ...
