Abstract: The article treats the problem of connection between the time of correlations of fluctuations and the radius of spatial correlation of complex amplitudes of signals of a complex target. Models of a ”rigid” and ”non-rigid” targets are viewed separately. It is asserted that signals received by a pair of analyzers spaced apart by a distance exceeding the radius of spatial correlation of the signals retain strong cross-correlation.

Keywords: spatial correlation radis, fluctuations correlation time, spaced-apart receivers-analyzers.
