Abstract
A method to determine a temperature of a product, the method includes: determining a dielectric constant as a function of a core-, surface-, and/or average-temperature correlation ε(T) of at least one product and storing the dielectric constant in a computer means; locating the product between a microwave-radiometry-antenna and a microwave-radiometry-receiver and measuring the dielectric properties of the product; selecting the correlation ε(T) that corresponds to the product whose dielectric properties have been measured, and calculating the core-, surface-, and/or average-temperature of the product using the dielectric constant correlation ε(T).
