Characterization of material to build radoms is important for their use in applications. The present procedure to do so was a heating test to determine material parameters at different temperatures. These tests did not include effects caused by wind and high pressure. In this presentation an experimental setup is described which simulates the exposure of the radom material to supersonic speed conditions. In particular this includes a specially designed antenna to look through the material laterally to get rid of effects caused by multipath propagation. Measurements at 35 GHz are also presented.
