1. A method of determining the far field RCS with near field spherical radar return data of an object with a stationary background thereabout including: (a) illuminating the object and stationary background with radar energy at a first wavelength, thereby causing stationary spherical radar energy to be reflected by the stationary background; (b) translating the object along a radial line-of-sight of the radar energy a distance of at least one half the first wavelength, thereby causing moving spherical radar energy to be reflected by the object; (c) detecting the moving spherical radar energy and the stationary spherical radar energy; and (d) separating the detected moving spherical radar energy from the detected stationary spherical radar energy.
