Abstract :
A case study of multipath fading on a microwave line-of-sight link is presented. Concurrent measurements by an aircraft-mounted refractometer are shown. Strong vertical and horizontal refractivity gradients are observed due to ground-based layering. Ray tracing shows three rays with subnanosecond separation and an angle-of-arrival spread of 0-4°. The fade is non-minimum-phase.
