Study of polarization dependent scattering anomalies with application to oceanic scattering

An analysis of anomalous scattering behavior is performed on various corrug ated surfaces relevant to oceanic scattering. In particular, it is shown th at HH to VV ratios larger than 1 are produced as a result of polarization a nomalies in the scattering returns. It is also shown that HH returns larger than those predicted by first-order perturbation theory do occur. These ca lculations thus provide the first evidence that some of the characteristics associated with "sea spikes," found in backscatter measurements from the o cean, can arise as a result of scattering from modulated wave trains. A qua litative and quantitative correlation is observed between our analysis and the water waves experiments of Lee et al. [1995].
