Forest Height Estimation Using a Single-Pass Airborne L-Band Polarimetric and Interferometric SAR System and Tomographic Techniques

This paper addresses forest height estimation for boreal forests at the test site of Edson in Alberta, Canada, using dual-baseline PolInSAR dataset measured by Intermap’s single-pass system. particular is acquired both ping-pong and non-ping-pong modes, which permit forming a TomoSAR configuration, i.e., an extreme configuration tomographic processing. A approach, based on polarimetric Capon MUSIC estimators, proposed to estimate elevation tree top underlying ground, hence estimated. The resulting DTM DSM over are validated against LiDAR-derived estimates, demonstrating undeniable capability L-band system monitoring.
