Abstract:

This paper presents a study of the electromagnetic scattering of a serpentine inlet at 15 GHz in Ku wave band. The radar cross section (RCS) characters of the serpentine inlet at different azimuths, attack angles and terminators are obtained. The results indicate that: (1) The average RCSs of the serpentine inlet with fan terminator in ±60°azimuth are-24.33 dB·m²in horizontal polarization and-19.15 dB·m² in vertical polarization. It means that the serpentine inlet is a low observable inlet.
