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.
