DOI: 10.1016/j.asr.2017.11.039
Abstract: Abstract In this paper we derive a closed-form solution to generate a backscatter power representation for both unfocused synthetic aperture radar altimetry and conventional altimetry signals in the frequency/slow-time domain. This new approach involves fast… read more here.

DOI: 10.1016/j.rse.2017.09.003
Abstract: Abstract Floodplains delay the transport of water, dissolved matter and sediments by storing water during flood peak seasons. Estimation of water storage over the floodplains is essential to understand the water balances in the fluvial… read more here.
