1. A method of estimating a transmission loss of radar signal through a vehicle component, the method comprising the steps of:
receiving a desired substrate criterion of a desired substrate, wherein the vehicle component comprises the desired substrate and a desired coating;
receiving a desired coating criterion of the desired coating;
physically measuring a plurality of known coating permittivities for the desired coating criterion at a plurality of different coating criteria values;
developing a model to estimate a desired coating permittivity using the plurality of known coating permittivities measured at the plurality of different coating criteria values;
receiving a coating criterion value, wherein the coating criterion value quantifies the desired coating criterion;
estimating the desired coating permittivity for the desired coating using the model; and
producing an estimated component transmission loss of radar signal through the vehicle component absent physical testing of the loss of radar signal through the desired coating.
