Microwave reflections are one of the basic errors associated with electromagnetic distance measurements. Measurements taken over an ice surface with a Tellurometer MRA-2 system show a definite trend of fine readings increasing with carrier frequency and large negative values as predicted by theoretical equations for reflections for a single surface. It was not possible to correlate these characteristics to surface reflections nor was it possible to correlate them with reflections from an atmospheric or subsurface layer.
