A computer processing technique has recently been described for the evaluation of monostatic scattering cross-sections of regularly shaped trihedral radar reflectors, the final stage of which involves the determination of an effective area mapped out by orthogonal projections of real and image aperture boundary lines on an oblique plane. Previously the area determination was carried out by an integration process plus a geometrical procedure. An alternative method described here reduces the area to a set of triangles which are evaluated and summed: this gives an exact value and is approximately 50 times faster in computer CPU time.
