Distribution function of the ground clutter and generalization of the Westerfield formula for calculation of the clutter power in spatially multichannel MIMO radar systems

Аннотация

On the basis of a phenomenological model of the Earth surface in the form of a set of statistically independent elementary scatterers, signals scattered by an extended random surface in spatially multichannel MIMO systems on moving carriers have been described. Generalizations of the clutter distribution function and the Westerfield formula for calculation of the clutter power in the considered case of linear motion of transmitting and receiving system elements for signals with large time–frequency product have been obtained.
