Understanding Multipath RF for Direction Finding
An introduction to multi-path RF signals. Using a real world environment we generate RF energy and watch how it effects its environment. How does this effect our ability to accurately locate the source using direction finding (DF) arrays? This animation is designed as a principal introduction only. Sharing a piece of training material we put together to help explain the effect of ‘multipath’ in the real world. It’s not designed to be a perfect model, but simply to show how different surfaces reflect RF back from both a moving point of origin and a moving point of view.
We look specifically at Angle of Arrival (AoA) Geolocation as it’s a common method that’s easy to explain. The CG environment used here was selected because it demonstrates multiple surface angles, complex objects (pagodas) and jagged bare rock alongside a variety of different organic surfaces.
