Abstract
In this paper, precision model, rough model and accurate model with YF-23 as original reference are established. The precision model is obtained by fine modeling based on pictures; the rough model is obtained by rough modeling based on pictures; the accurate model is obtained by fine modeling based on point cloud model. Three models correspond to three modeling methods in engineering practice. Based on the multilevel fast multipole algorithm (MLFMA), the vertical polarization transmitting/vertical polarization receiving (VV) and horizontal polarization transmitting/horizontal polarization receiving (HH) radar cross section (RCS) characteristics of three models were simulated at low and high frequencies. The relationship between aircraft surface details and radar stealth performance were investigated and analyzed according to the simulation results.
