Microwave, unlike visible light, can be measured directly on the phase of the wave. The measurement of complex amplitude suggests a possibility of holographic plasma imaging with a single view-field of planar array of detectors. In this paper, an inverse problem of holography is formulated with respect to reflection and scattering wave observations. Against the restricted view-field and few detectors, a solution of Tikhonov type is proposed and examined by numerical simulations. The first result of feasibility study is presented.
