Mapping Topography and Forest Parameters in a Boreal Forest with Dual-Baseline TanDEM-X Data and the Two-Level Model

Paper in proceedings, 2016

In this paper, two-level model (TLM) inversion is used for unsupervised mapping of ground topography, forest height, and canopy density in boreal forests from dual-baseline, alternating bistatic mode TanDEM-X data. The TLM models forest as two discrete scattering levels, ground and vegetation, the latter with gaps. It is here shown using two alternating bistatic-mode TanDEM-X acquisitions made over the Swedish boreal test site Krycklan in September 2011 that the inverted TLM parameters can be used for mapping of ground topography and forest parameters.
