Deconvolution method of near-far field translation

Deconvolution method of near-far field translation based on the plane wave spectra and deconvolution theory transforms near-field scattering information of target measurement to far-field scattering information of target, which is based on the chain relation between the near-field scattering and far-field RCS. The paper analyzes the problems during the deconvolution. A good agreement is tested by the simulation of near-far field translation of the slim and ideal conducting flat plate. The deconvolution method of near-far field translation is significant in the aspects of target feature research, near-field scattering measurement and the far-field RCS measurement.
