Using FEKO To Calculate Radar Cross Section Of Aircrafts With Engine Inlets

Asymptotic methods are the preferred method for calculating the radar cross section (RCS) of targets like aircrafts since the main parts of the target are more than an order of magnitude larger than the wavelength. However, an engine inlet with fan blades will need a more rigorous calculation method, such as the multi-level fast multipole method (MLFMM). This presents the challenge of combining a rigorous method with an asymptotic method to compute the RCS of an aircraft with engine inlets. Download this with paper for a two-step method offering a solution that obtains accurate calculation results in a limited amount of time.
