Scattering Mechanisms for the "Ear" Feature of Lop Nur Lake Basin
Lop Nur is a famous dry lake in the arid region of China. It was an important section of the ancient “Silk Road”, famous in history as the prosperous communication channel between Eastern and Western cultures. At present, there is no surface water in Lop Nur Lake basin, and on SAR (Synthetic Aperture Radar) images, it looks like an “Ear”. The objective of this paper is to interpret the Lop Nur ...
متن کاملPrecise topography assessment of Lop Nur Lake Basin using GLAS altimeter
Lop Nur is a dried-up salt lake lying in the eastern part of Tarim basin, which used to be the second largest lagon in China. The “ear” rings in Lop Nur attract many interests and are regarded as the lake shorelines during its recession. The topography of the lake basin is important in understanding the formation of the “ear” rings. In this paper, elevation data along three transects obtained f...
متن کاملSalt Content Distribution and Paleoclimatic Significance of the Lop Nur "Ear" Feature: Results from Analysis of EO-1 Hyperion Imagery
Lop Nur, a playa lake located on the eastern margin of Tarim Basin in northwestern China, is famous for the “Ear” feature of its salt crust, which appears in remote-sensing images. In this study, partial least squares (PLS) regression was used to estimated Lop Nur playa salt-crust properties, including total salt, Ca, Mg, Na, Si, and Fe using laboratory hyperspectral data. PLS results for labor...
متن کاملAnalyzing the "Ear" feature of a dried up lake based on volume scattering modelling
Lop Nur is a famous dried lake in Xinjiang of northwest China and finally lost its last drop of water in 1960s. It is well known for its “Human Ear Shape” feature in optical remote sensing images. Likewise, “Ear” feature is shown in Synthetic Aperture Radar (SAR) images, and even larger because of penetration effect [1, 2]. There are some explanations about external causes of the “Ear” feature ...
متن کاملStudy on the polarimetric characteristics of the Lop Nur arid area using PolSAR data
The quantitative study of the arid Lop Nur lake basin is significant to investigate the environmental changes in the arid area of northwestern China and extremely arid areas of Eurasia in general. Synthetic aperture radar (SAR) imagery, with its penetration capability and advantages for studying geological phenomena on a large spatial scale, is very suitable for analyzing the subsurface of the ...
