Poyang Lake is the largest freshwater lake in China with an area of about 3,000 km2. Its wetland ecosystem has a significant impact on China' s environment change. Traditional way to monitor biomass c...
Agricultural activities affect strongly their environment. Therefore and because of their other economic, industrial and political effects, monitoring agricultural areas is increasingly demanded. Spac...
ASAR image target detection and recognition has been always a hot research. In this paper, on the foundation of the previous studies, a target recognition method based on combined wavelet transformati...
Atmospheric water vapour effects represent a major limitation of repeat-pass Interferometric SAR (InSAR) techniques including InSAR time series approaches (e.g. permanent scatterers (PS) and small bas...
Due to the accelerating global warming, droughts which cause severe damages especially in the agriculture became a very recurrent phenomenon in all over the world. Monitoring the characteristics of so...
In this paper, a practical scheme for assimilation of multi-temporal and multi-polarization ENVISAT ASAR data in rice crop model to map rice yield has been presented. To achieve this, rice distributio...
The present study addresses the potential of Synthetic Aperture Radar (SAR) data for land cover classification in parts of Dandeli forested regions, Karnataka, India. a FCC has been generated from coh...
The object of this paper is taking full advantage of ENVISAT ASAR image in differentiating land and water area based on the research of ASAR image character, to work out a efficient method to monitor ...
As confirmed by many scientists, atmosphere has intensive contaminative role on Interferometric Synthetic Aperture Radar (InSAR) measurements. Atmospheric parameters, always influence radar’s phase bu...
Space borne radar data facilitates continuous monitoring of almost any location on the earth (limitations in polar zones) at quite low costs. Almost weather-independent operation of radar systems enab...
This study aims to assess the contribution of ENVISAT ASAR data for the monitoring of the littoral plains of Kourou and Saint Laurent du Maroni (French Guyana).
Human activities strongly affect the environment and impact natural resources. To reduce the disadvantages, we have to monitor the human activities as well as the environment. Therefore demand on con...
Recent studies have shown the potential of Synthetic Aperture Radars (SAR) for mapping of rice fields and some other vegetation types. For rice field classification, conventional classification tech...
对流层水汽引起的大气相位延迟是制约重复轨道InSAR 高精度测量的重要因素之一。为有效解决InSAR 中大气相位延迟的问题,对InSAR 中大气延迟误差进行了分析,研究了利用MODIS 水汽数据对ASAR 干涉图大气改正的方法及其关键技术,并以太原地区的ASAR 干涉图为例,对其进行大气改正。实验结果表明,MODIS/ASAR 大气改正方法可以显著地提高干涉图的质量,同时形变反演的精度也得到了明显...
概述了PSInSAR方法的技术流程,阐述了定标ENVISAT ASAR数据对PS候选点(Persistent Scatterer Cadidate,PSC)筛选 的作用。研究表明:对ENVISAR ASAR 数据进行定标有助于筛选出更多的PS候选点;以定标得到的后向散射系数作为阈值,可以剔 除散射信号统计特性较稳定但散射强度低的像素点,从而避免可能由这些点引入的相位误差。在初步实现PSInSA...
