The amplitude analysis of radar signals from rain is refined. Uniform rain return details with amplitude weighting due to 1) range gate straddle losses and 2) rain attenuation within the processed range cell, both respectively and in nonlinear resultant conditions, are considered. The resulting factor is small in magnitude, except in heavy rain and short wavelengths. The factor has a data-dependent analytic form, without a known analytic inverse. A quantitative solution for the reflectivity factor may employ numerical look-up tables parameterized in specific attenuation single parameter coefficients and range gate width.
