Research on RCS shielding scheme for parked aircraft based on FEKO
Due to the large size of grounded aircraft and the difficulty in using shielding cloth to completely cover the aircraft, it is necessary to study efficient RCS shielding schemes for grounded aircraft to ensure that they can quickly hide on the spot. By covering key parts, the RCS of the aircraft can be reduced, the probability of being detected by radar can be reduced, and the survival rate of the aircraft can be improved. The geometric model of the aircraft is established using SolidWorks, and the RCS distribution of the electromagnetic model is determined by FEKO simulation calculation. Suitable shielding materials are selected to design the shielding scheme, and the radar characteristics of the shielding model are simulated and calculated. The effectiveness of the shielding scheme is evaluated by comparing the RCS distribution with the numerical change results. The study found that using magnetic absorbers combined with high-toughness epoxy resin materials reduced the average RCS by 10.757 dBm<sup>2</sup> at a frequency of 9.14 GHz after coating the aircraft model, providing a theoretical basis for practical applications.
