Synthetic-aperture radar (SAR) is a form of radar that is used to create two-dimensional images or three-dimensional reconstructions of objects, such as landscapes. [1] SAR uses the motion of …

2020年5月28日 · 本研究将传统的SAR扩展到多样性-面积关系 (diversity area relationship, DAR)。 选取了三种DAR模型：传统的幂律分布 (power law, PL)；指数截断的幂律分布 (PLEC, PL …

The special administrative regions (SAR) of the People's Republic of China are one of four types of province-level divisions of the People's Republic of China directly under the control of its …

We investigate SAR performance and processing of sparse, multiple-aperture arrays. Three filters are evaluated: the matched filter, maximum-likelihood filter, and minimum mean-square error …

High Resolution Wide Swath Imaging (HRWS) with spaceborne SAR systems has received major attention over the recent years [1]- [6]. The favored concepts embark on

Experimental results show that the proposed method gives promising results in SAR image (including large area SAR image) segmentation and effectively suppresses the influence of …

2018年9月25日 · In this study, I extend the SAR to general DAR systematically by adopting the Hill numbers as diversity measures, for both alpha-diversity and beta-diversity scaling over …

2023年11月24日 · In this article, we propose a novel method that parameterizes the time-varying area observed by the spaceborne SAR operating in the boresight stripmap mode into a fixed …

SAR is calculated as: resolution^2 * cos ( (degrees (slope) * (pi / 180)) ) Berry, J.K. (2002). Use surface area for realistic calculations. Geoworld 15 (9):20-1. Jeffrey S. Evans …

2025年1月10日 · The species−area relationship (SAR) was developed to capture differences in the number of species at different spatial scales and the turnover of species between small …
