Moment extraction

The autocorrelations are the basis for Doppler moment calculations:

• Mean velocity—from Arg [ R1 ]
• Spectrum width—from |R1| and |R2| assuming Gaussian spectrum
• dBZ— from |R0| with correction for ground clutter, system noise, and gaseous attenuation. Uses calibration information supplied by host computer
• dBT—identical to dBZ, but without ground clutter

These standard parameters are output to the host application.
