Design approach of a novel wideband slotline antenna is proposed. An offset-fed structure is applied to simultaneously excite the first three radiation modes within a slotline radiator, without introducing external less-radiative resonant modes. By controlling the excitation of its full-wavelength radiation mode, the proposed slotline antenna exhibits a frequency-spatial steerable notch-band characteristic...
Since the terrain slope cannot be neglected for forest height inversion with polarimetric synthetic aperture radar interferometry (PolInSAR), a sloped random volume over ground (S-RVoG) model is proposed to correct the terrain distortion for forest parameters estimation. A significant model complexity reduction is achieved by aligning the reference frame along the local terrain slope and changing...
