Abstract :
This analysis develops an innovative image reconstruction technique for synthetic aperture radar (SAR) based upon the removal of multiple-bounce (MB) artifacts. The basic concept is that the phase history measurements include the realistic effects of MB interactions. These measured phase history data are decomposed into contributions due to the desired single-bounce (SB) scattering events and the undesirable MB interactions. An enhanced quality image can be constructed by retaining only the SB contributions.
