Assessment of the impact of long integration time in Geosynchronous SAR imagery of agricultural fields by means of GB-SAR data

Geosynchronous synthetic aperture radar (GeoSAR) missions offer the advantage of near-continuous monitoring of specific regions on Earth, making them essential for applications that require continuous information. However, wind-induced motion along the inherent long integration time can result in im...

However, wind-induced motion along the inherent long integration time can result in image defocusing, with potential degradation of retrieved information. This article aims to investigate the impact of GeoSAR long integration time in synthetic aperture radar (SAR) imaging and derived products (time series of backscatter and coherence) required to extract agriculture-relevant soil or crop parameters of interest. The study is based on the extensive HydroSoil data acquisition campaign carried out over barley and corn crops, funded by the European Space Agency. The collected raw data are used to synthesize equivalent apertures with integration times of up to 4 h, similar to those acquired with a GeoSAR. These ultraslow apertures facilitate the assessment of the impact of agricultural scene decorrelation on the generation of images with extended integration times.This work was supported in part by the European Space Agency (ESA Contract 4000132509/20/NL/FF/ab with UPC) and in part by the Spanish MCINN funds Unidad de Excelencia Maria de Maeztu MDM-2016-0600, under Project PID2020-117303GBC21/AEI/10.13039/501100011033, and under Project PID2020-117303GBC22/AEI/10.13039/501100011033.Peer ReviewedInstitute of Electrical and Electronics Engineers (IEEE)20242024-01-0120232023-12-21journal articlehttp://purl.org/coar/resource_type/c_6501VoRhttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleapplication/pdfhttps://hdl.handle.net/2117/398451https://dx.doi.org/10.1109/JSTARS.2023.3338468reponame:UPCommons.
