11.5.3. Circular Flat Plate
Fig. 11.19
shows a circular flat plate of radius , centered at the origin. Due
to the circular symmetry, the backscattered RCS of a circular flat plate has no
dependency on . The RCS is only aspect angle dependent. For normal inci-
dence (i.e., zero aspect angle) the backscattered RCS for a circular flat plate is
