摘要

The accuracy with which MLFMM, PO and PO with SBR can calculate the RCS of a realistic electrically large model airframe is investigated. The target has a maximum electrical length of 106 lambda. An accurate 3D numerical model of the target was created using a laser scanner. The numerical results are validated against data measured in a compact range.
