Sar for Agriculture: Advances, Problems and Prospects
نویسنده
چکیده
Then, the paper considers three aspects of the retrieval problem, corresponding to three fundamental steps: i) identification of a convenient radar configuration; ii) development of reliable relationships between backscatter coefficient and agricultural variables (direct problem); iii) retrieval in the strict sense (inverse problem). For each of the three topics, the important recent advances are summarized and the author’s point of view about the state of the art is given.

An Augmented Lagrangian Method for Sparse SAR Imaging
In this paper, we present a solution to the constrained l1-norm minimization problem for sparse SAR imaging. The techniques rely on the recent advances in the solution of optimization problems, based on the Augmented Lagrangian Methods (ALMs), namely the Alternating Direction Method of Multipliers. Here, we present an application of CSALSA (an ALM for constrained optimization problems) to SAR i...

متن کاملA study of salinity variation (EC & SAR) in agricultural lands, Kermanshah province
Soil salinity is one of the problems threatening agricultural lands. Parts of this phenomenon are related to geologic formations and saltpans, while some major factors are resulted from irrelevant agricultural activities, issue of irrigation, and improper cultivation systems which lead to increase in soil salinity. To avoid such consequences that would end up with ecosystem degradation, suitabl...
