Radar Cross Section Eugene F Knott Pdf Better Link

One of Knott's significant contributions is the development of the Physical Optics (PO) method, which is widely used for RCS prediction. The PO method approximates the scattering of radar waves from a target by assuming that the target surface is locally planar and that the radar wave interacts with the surface as if it were a flat plate. This method has been successfully applied to predict the RCS of various targets, including aircraft and ships.
