An Accurate Multistatic Radar RCS (MRCS) for Airhawk F117 Stealthy Target

This paper is devoted to model a multistatic radar cross section MRCS for F117 stealthy target. The model predict the target aperture area using a scaled model measurements in order to achieve a long scale electromagnetic RCS for the modeled aircraft. The target MRCS is modeled as a function of the electromagnetic wave incident angle, its polarization, target azimuth angle, elevation angle, and the electrical characteristic of the stealthy coating material. The results give accurate RCS for the target for all azimuth angles and from 0 to 70 degree of the elevation angles compared with the fixed RCS of F117 target reported as 0.025 m².
