Abstract

The authors study the angular correlation function (ACF) of a rough surface and volume scattering and apply it to the detection of a target embedded in the clutter. Both the 2D and 3D ACF are studied by using numerical simulations with frequency averaging and circular azimuthal angle averaging techniques. The 3D case has an increase of degree of freedom over the 2D case. This increase of freedom makes the circular azimuthal angle averaging more successful in suppressing the clutter, making the technique attractive in real life implementation
