1. A method comprising:

  • propagating a radar signal into a region of interest using a dual polarization radar transmitter;

    collecting dual polarization radar echo data scattered form within the region of interest, wherein the radar echo data comprises horizontal and vertical complex voltages;

    calculating, using an electronic computer processor, a covariance matrix from the radar echo data; and

    estimating, using an electronic computer processor, precipitation profiles from an off-diagonal element of the covariance matrix.
