Comparing performances of RVoG and OVoG crop height inversion schemes from multi-frequency SAR data

Abstract

In this work, we assess the plausibility of the Random Volume over Ground (RVoG) assumption in relation to crop height estimation. For this reason, two dual-baseline Random-VoG and Oriented-VoG inversion schemes have been developed and applied to a dataset of fully-polarimetric F-SAR measurements over an agricultural area in Germany. Preliminary results for the wheat case study indicate a positive relation between the bias of the estimated height and the differential extinction when the Random-VoG inversion scheme is used.
