The system for measuring characteristics of scatterers by spaced receiver
remote sensors uses a method based on calculation and analysis of the
auto- and cross-structure functions for return signals. The method
enhances operational capabilities of spaced receiver remote sensors by
providing a diverse body of characteristics of scatterers at any elevation
angle independently of a type of remote sensor, a type of scatterers, a
number of scatterers and their spatial distribution within the illuminated
volume. A list of characteristics includes (but is not limited by) the
mean speed of scatterers, intensity of the speed fluctuations, and a set
of indicators for identification of scatterers. The method is not so
sensitive to ground clutter and hard targets as the existing methods are.
The method allows to increase an effective signal-to-noise ratio for the
existing spaced antenna remote sensors by using significantly overlapping
antennas. The method allows to simplify the existing hardware by removing
the quadrature-phase synchronous detector although it can be applied to
the standard complex output signal.
