Abstract

Abstract:

The method of the synthetical basis function (SBFS) is introduced to analyze the scattering problem of the large array antennas. Based on the solution of the electromagnetic problems, the method accomplishes regional partition of the geometrical and physical structure of the model and brings in an equivalent current source to take the coupling between elements into consideration, thus obtaining the space of the SBFS. Compared with the conventional partition of the matrix, the method proposed in this paper can further release the heavy burden on the CPU in terms of memory and time. Therefore, this method can effectively analyze the scattering problem of large array antennas on PCs. Practical examples are analyzed using both this novel method and the conventional MoM. The comparison shows that the error of RCS is less than 2dB, which demonstrates the accuracy and efficiency of the SBFS.

Key words: synthetical basis functions, method of moments, scattering, radar cross section
