Abstract :
A new full-wave theory for scattering from rough dielectric surfaces-called the correction current (CC) method-is presented. An iterative solution is developed leading to a first-order scatter pattern in the form of a single integral, making it computationally efficient and capable of showing surface parameter dependencies explicitly. The first-order CC-scatter solution is shown to satisfy reciprocity, to comply with a pattern symmetry relation, and to be accurate over a wide range of surface parameters. The theory is also shown to be capable of quantifying its field errors resulting in an error criterion that is derived from the theory itself (which is not generally available in other theories). Radar cross sections for random rough surfaces with Gaussian statistics are compared to data generated by solving the electric field integral equation using the method of moments. Good agreement was shown to result for a wide range of surface parameters.
