In this study, according to the characteristics of the study area, an advanced integral equation model was used for numerical simulation analysis to establish a database of surface microwave scattering characteristics under sparse vegetation cover. Thus, a soil moisture retrieval model suitable for arid area was constructed. The results were as follows: (1) The response of the backscattering coefficient to soil moisture and associated surface roughness is significantly and logarithmically correlated under different incidence angles and polarization modes, and, a database of microwave scattering characteristics of arid soil surface under sparse vegetation cover was established. (2) According to the Sentinel-1 radar system parameters, a model for retrieving spatial distribution information of soil moisture was constructed; the soil moisture content information was extracted, and the results were consistent with the spatial distribution characteristics of soil moisture in the same period in the research area. (3) For the 0\u201310 cm surface soil moisture, the correlation coefficient between the simulated value and the measured value reached 0.8488, which means that the developed retrieval model has applicability to derive surface soil moisture in the oasis region of arid regions. This study can provide method for real-time and large-scale detection of soil moisture content in arid areas.<\/jats:p>","DOI":"10.3390\/s19030589","type":"journal-article","created":{"date-parts":[[2019,1,30]],"date-time":"2019-01-30T15:58:27Z","timestamp":1548863907000},"page":"589","source":"Crossref","is-referenced-by-count":42,"title":["Soil Moisture Retrival Based on Sentinel-1 Imagery under Sparse Vegetation Coverage"],"prefix":"10.3390","volume":"19","author":[{"given":"Shuai","family":"Huang","sequence":"first","affiliation":[{"name":"College of Resources and Environment Sciences, Xinjiang University, Urumqi 830046, China"},{"name":"Key Laboratory of Oasis Ecology under Ministry of Education, Xinjiang University, Urumqi 830046, China"}]},{"given":"Jianli","family":"Ding","sequence":"additional","affiliation":[{"name":"College of Resources and Environment Sciences, Xinjiang University, Urumqi 830046, China"},{"name":"Key Laboratory of Oasis Ecology under Ministry of Education, Xinjiang University, Urumqi 830046, China"}]},{"given":"Jie","family":"Zou","sequence":"additional","affiliation":[{"name":"College of Resources and Environment Sciences, Xinjiang University, Urumqi 830046, China"},{"name":"Key Laboratory of Oasis Ecology under Ministry of Education, Xinjiang University, Urumqi 830046, China"}]},{"given":"Bohua","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Resources and Environment Sciences, Xinjiang University, Urumqi 830046, China"},{"name":"Key Laboratory of Oasis Ecology under Ministry of Education, Xinjiang University, Urumqi 830046, China"}]},{"given":"Junyong","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Resources and Environment Sciences, Xinjiang University, Urumqi 830046, China"},{"name":"Key Laboratory of Oasis Ecology under Ministry of Education, Xinjiang University, Urumqi 830046, China"}]},{"given":"Wenqian","family":"Chen","sequence":"additional","affiliation":[{"name":"College of Resources and Environment Sciences, Xinjiang University, Urumqi 830046, China"},{"name":"Key Laboratory of Oasis Ecology under Ministry of Education, Xinjiang University, Urumqi 830046, China"}]}],"member":"1968","published-online":{"date-parts":[[2019,1,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"301","DOI":"10.1002\/grl.50108","article-title":"Irrigation in California\u2019s Central Valley Strengthens the Southwestern U.
