Application of GO Management in Bistatic RCS Computation Using the Vector Parabolic Equation Method

الملخص EN

The parabolic equation (PE) method is a good choice in solving large-scale problems, but the resultant matrix is usually ill conditioned.

In this letter, we introduce the geometric optics (GO) management in the calculation of bistatic radar cross sections using three-dimensional vector PE method.

This method manages the object surface by GO, and hence the ill-conditioned problem can be avoided.

Examples are given using the presented method, original method, and the method of moments.

Results show the validity and stability of the presented method.
