  • System for measuring characteristic of scatterers using spaced receiver remote sensors
    Patent number: 6512996
    Abstract: 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.
