The finite element method is employed to solve coupling scattering from a scatter target over a randomly rough surface. The angular correlation function (ACF) of scattering waves from a randomly rough surface is generally small away from the memory line. However, it is expected that enhancement on non-memory line of the ACF can be used to detect a target placed over the rough surface. This paper presents numerical results of ACF for detection of a scatter target over randomly rough surface by using the finite element method.
