摘要

Along-Track Interferometry (ATI) for the indication of moving targets with two channel Synthetic Aperture Radar (SAR) shows a low detection probability for a small number of looks. This paper proposes an enhancement called Better ATI (BATI). It is characterized by a constant parameter added to the interferometric SAR image before determining its phase. Statistical analysis shows that the new technique significantly outperforms ATI, is comparable to Displaced Phase Center Antenna (DPCA) for homogeneous terrain and may outper-form DPCA in heterogeneous terrain. The theoretical results are confirmed successfully with experimental data.
