The invention discloses a dual-polarization Doppler
weather radar ground
clutter inhibition method based on
fuzzy logic, and the method comprises the steps:
processing volume scanning data of a dual-polarization Doppler
weather radar into 360 radial lines, wherein the interval between each two adjacent radial lines is one degree, and the data of each
radial line comprises seven echo characteristic physical quantities: intensity, a mean Doppler speed, a spectrum width, a difference
reflectivity factor, a difference propagation phase shift, and a
correlation coefficient; setting the seven physical quantities which respectively comprise the intensity, the mean Doppler speed, the spectrum width, the difference
reflectivity factor, the difference propagation phase shift, and the
correlation coefficient; enabling seven fuzzy results to be assigned with corresponding weight values, carrying out accumulating and obtaining a ground
clutter criterion of one echo point; Determining that the intensity echo of the point is the ground
clutter when the ground clutter criterion of one echo point is greater than a threshold value; inhibiting the ground clutter of the dual-polarization Doppler
weather radar through the ground clutter criterion of each echo point, and compensating a hole of a current layer after clutter inhibiting through employing the
echo intensity value of a corresponding point in an upper layer in the volume scanning data.
