Abstract
The effect of sea swells on the performance of radar tracking at low angle geometries is addressed in this report, through development of a surface scattering model and via computer simulation studies. Sea swells are systematic perturbations of the ocean surface and, as such, could introduce biases into estimation algorithms and/or add focusing effects, thus complicating the nature of the multipath signal. This would lead to measurement instability that would be detrimental to the general performance of radars and, in particular, to the performance of angle-of-arrival estimation algorithms as applied to sampled aperture data in a low angle tracking scenario.
