With the upcoming L-band Synthetic Aperture Radar (SAR) satellite mission Radar Observing System for Europe L-band SAR (ROSE-L) and its integration into existing C-band satellite missions such as Sentinel-1, multi-frequency SAR observations with high temporal and spatial resolution will become available. The SARSense campaign was conducted between June and August 2019 to investigate the potential for estimating soil and plant parameters at the agricultural test site in Selhausen (Germany). It included C- and L-band air- and space-borne observations accompanied by extensive in situ soil and plant sampling as well as unmanned aerial system (UAS) based multispectral and thermal infrared measurements. In this regard, we introduce a new publicly available SAR data set and present the first analysis of C- and L-band co- and cross-polarized backscattering signals regarding their sensitivity to soil and plant parameters. Results indicate that a multi-frequency approach is relevant to disentangle soil and plant contributions to the SAR signal and to identify specific scattering mechanisms associated with the characteristics of different crop type, especially for root crops and cereals.

SARSense活动:空运和空运C波段和L波段SAR用于分析农业土壤和植物参数

随着即将推出的用于欧洲的L波段合成孔径雷达(SAR)卫星任务雷达观测系统L波段SAR(ROSE-L)及其与现有C波段卫星任务(如Sentinel-1)的集成,可以进行多频SAR观测时空分辨率很高。SARSense活动于2019年6月至2019年8月进行,旨在调查在Selhausen(德国)的农业试验场估算土壤和植物参数的潜力。它包括C波段和L波段的空中和太空观测,并伴有大量的原地土壤和植物采样以及基于无人飞行系统(UAS)的多光谱和热红外测量。在这方面,我们介绍了一个新的公开可用的SAR数据集,并就其对土壤和植物参数的敏感性,对C波段和L波段共极化和交叉极化的反向散射信号进行了首次分析。结果表明,多频方法与解开土壤和植物对SAR信号的贡献有关,并确定与不同作物类型(尤其是块根作物和谷类)特征相关的特定散射机制。
