Altitude estimation of RF interference sources via interferometric corrections

Gys

> We conduct a preliminary study using a two-minute observation from the Murchison-Widefield Array (MWA) in which an unknown object briefly crosses the field of view, reflecting RFI signals into the array. By applying near-field corrections that bring the object into focus, we are able to estimate its approximate altitude and speed to be 11.7 km and 792 km/h, respectively. This allows us to confidently conclude that the object in question is in fact an airplane.

Very cool.
