Research on Component RCS Analysis for Unmanned Aerial Vehicle

In this paper, an analysis method of component RCS is proposed and applied to analyze the unmanned aerial vehicles (UAVs). The matrix equation is constructed with the whole structure and solved by multilevel fast multipole algorithm (MLFMA). The local currents of the component are extracted to implement the component radar cross section (RCS) calculation. The component RCS results, which include the coupling effects between components, can accurately represent the effect of the component on the whole structure. Finally, two types of UAV are simulated by the proposed method to present the component RCS analysis.
