Special Issue Information
Dear Colleagues,
Spaceborne radar observations have been demonstrated for the monitoring of vegetation dynamics, retrieval of crop growth variables, and soil moisture in many studies. There are several spaceborne radar sensors which are operated at different frequencies bands, such as Ku band (Quicksat and Scatsat-1), X-band (TerraSAR-X and COSMO SkyMed), C-band (Sentinel-1 and Radarsat-2), and L-band (ALOS PALSAR and SAOCOM). As a well-settled science, the amount of backscattering depends on the wavelength and polarization of the microwave signal and shape and size of the scatter. Spaceborne sensors are operated in the wide range of microwave frequencies, and different polarizations may be useful to gather the valuable information of agriculture and soil surface studies for different purposes. The most important advantage of radar remote sensing is the ability to establish a great understanding of vegetation backscatter from agricultural crops at a field level due to its high-resolution capability compared to passive microwave sensors. It may be very useful for improved soil moisture retrieval from agricultural fields, agricultural crop monitoring, and for the study of drought water stress. The different applications of spaceborne radar data in the field of agricultural and soil moisture are considered here, such as water resource management, drought/flood monitoring, irrigation management, and hydrological studies.
This Special Issue focuses on state-of-the-art research in spaceborne radar remote sensing related to agriculture and soil moisture applications. Contributions are invited for agriculture and soil moisture applications using different spaceborne radar sensors in various technical aspects, such as a wide range of frequencies (from Ku-band to L-band) and polarizations, new processing techniques, scattering theory, retrieval approaches, field experiments, data fusion, and assimilation. Contributions are also accepted relating to the operational use of spaceborne radar observations for decision-making, and the services provided to farmers for agricultural growth. The submissions can cover but need not be limited to the following topics:
- Spaceborne radar remote sensing of agriculture and soil moisture retrieval;
- Advances in polarimetric spaceborne radar applications of the agriculture and soil moisture;
- The retrieval methods for soil moisture using spaceborne radar remote sensing;
- The modeling for the retrieval of crop growth variables using spaceborne radar remote sensing;
- Spaceborne radar remote sensing for agro-hydrological modeling;
- Spaceborne radar remote sensing for irrigation scheduling;
- Spaceborne radar remote sensing for drought/flood monitoringl
- Related topics to the agricultural hydrology and water resources modeling using spaceborne radar remote sensing;
- Any other related topic.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sensors is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
