Abstract: In the system of three spatially-diversed mutually coherent receivers, the phase structure of an electromagnetic field is determined - the hologram generated by the moving radiation source and objects irradiated by this source. Change of curvature of the signal wave-front depending on an effective reflecting surface and location of irradiated objects is defined. By experimental example of radio signal reception from the moving source by means of expansion of wave-front curvature changes with use of wavelet transformation, formation of two-dimensional panoramic radio image of the objects in the sector of control is carried out.

Keywords: coherent receivers, hologram, radiolocation, wavelet transformation.
