reed on compact plaur and pure reed vegetation.
17.7.6 Temporal Intensity Radar Data Signature
Our analysis will primarily address the different reed classes (Figs. 17.19 and
17.20).
On average, the temporal variation is similar whatever the polarization, VV or
VH; from 2014 November to 2015 January, the radiometry is not really changing
because at this period the landscape is not changing very much. In March in early
