Potential of P-Band SAR Tomography in Forest Type Classification

open access: yesRemote Sensing, 2021
Forest type classification using spaceborne remote sensing is a challenge. Low-frequency Synthetic Aperture Radar (SAR) signals (i.e., P-band, ∼0.69 m wavelength) are needed to penetrate a thick vegetation layer.
