A technique is presented for calculating the radar cross section of a conducting cone-sphere as a function of cone angle, aspect angle, tip radius, base radius, and wavelength for both cw and short-pulse incident signals. A modification of the physical optics approximation is used in which the incident sinusoidal wave is replaced by a pulse of triangular waves, permitting the physical optics integrals to be replaced by finite summations. Creeping waves are included by using the known results for a sphere combined with an aspect- angle dependence obtained from a ray-tracing model. For long incident pulses, the calculated cross sections show good agreement with cw measured values. For short incident pulses, the behavior of individual scattering centers may be studied as a function of the target parameters.
