Distinguishing the density of rock wool is an important part in its production process. One available common option for inline measurements of the density is based on X-rays.
Due to huge security requirements in realising such measurements, this method is very complex and expensive. This paper
investigates a method to find a relationship between radar based
measurements and the density of rockwool. This is shown by
evaluating the measurements of amplitude and phase of several
rock wool samples with different densities. The results show a
linear dependency of the measured phase values and the surface
weights of the given samples.
