Drift inversion estimation of multipath ghosts in SAR image reconstruction
Conventional SAR image formation includes the effects of only direct-scattering events. However, multipath events can be included in the measured phase history data. These multipath effects appear as "ghosts" in SAR images, thereby creating adverse image reconstructions. In order to separate the direct scatterers from the multipath scattering effects, an image reconstruction algorithm for multipath scattering (IRAMS) is applied. This method incorporates a wavelet-like inversion estimate of the multipath ghosts.
