In overeem11/RAINLINK: Retrieval algorithm for rainfall mapping from microwave links in a cellular communication network.

Subfunction for path-averaged rainfall estimation from minimum and maximum attenuations from microwave links.

Description

Subfunction for path-averaged rainfall estimation using microwave links. Compute minimum (Amin) and maximum (Amax) attenuation over the link path. Convert these to minimum and maximum path-averaged rainfall intensities. Convert minimum and maximum path-averaged rainfall intensities to mean path-averaged rainfall intensities.

Works for a sampling strategy where minimum and maximum received signal powers are provided, and the transmitted power levels are constant.

Also works for a sampling strategy where instantaneous transmitted and received signal levels are obtained. In case of instantaneous signal levels, it does not matter whether transmitted power levels vary or are constant. The only requirement is that the input data for RAINLINK needs some preprocessing. See ”ManualRAINLINK.pdf” for instructions.

Also works for a sampling strategy where average transmitted and received signal levels are obtained. In case of average signal levels, it does not matter whether transmitted power levels vary or are constant. The only requirement is that the input data for RAINLINK needs some preprocessing. See ”ManualRAINLINK.pdf” for instructions.

Usage

MinMaxRSLToMeanR(a, Aa, alpha, b, PathLength, PmaxCor, PminCor, Pref)

Arguments

a	Coefficients in relationship between rainfall intensity and specific attenuation (mm h^{-1} dB^{-b} km^{b}).

alpha	Coefficient (\alpha) determining contribution of minimum and maximum path-averaged rainfall intensity to mean path-averaged rainfall intensity (-).
b	Exponents in relationship between rainfall intensity and specific attenuation (-).
PathLength	Lengths of link paths (km).

Value

Data frame with mean path-averaged rainfall intensities (mm h^{-1}).
