Sy. Wang et Sk. Jeng, A DETERMINISTIC METHOD FOR GENERATING A SCATTERING-CENTER MODEL TO RECONSTRUCT THE RCS PATTERN OF COMPLEX RADAR TARGETS, IEEE transactions on electromagnetic compatibility, 39(4), 1997, pp. 315-323
This paper presents a deterministic method to establish the scattering
-center model for complex radar targets, By this method, high frequenc
y techniques including physical optics, physical theory and diffractio
n and shooting and bouncing rays are used to establish scattering cent
ers, Numerical results show that, by using this method with only singl
e-frequency scattering centers at large aspect increments, the RCS pat
tern at finer aspect increments is well reconstructed; besides, it can
be extended to predict the RCS pattern at any frequency of interest i
n a required narrow bandwidth, Good agreement between direct RCS calcu
lation, scattering-center model and measured results is obtained.
