Stable and Fast Method for Solving Bistatic RCS of Three-dimensional Objects

To enhance the time performance and stability of the compressive sensing-based method of moments for solving the bistatic radar cross section of three-dimensional objects, a novel method is proposed in this paper. Several rows of the impedance matrix are uniformly extracted to construct the measurement matrix, and the characteristic modes based on domain decomposition are introduced as sparse transformation matrix. Numerical results demonstrate that the proposed method can provide more stable results and significantly reduce the computation time.
