Just where exactly is the radar? (a.k.a. the radar antenna phase center)

Doerry, Armin

The "location" of the radar is the reference location to which the radar measures range. This is typically the antenna's "phase center". However, the antenna's phase center is not generally obvious, and may not correspond to any seemingly obvious physical location, such as the focal point of a dish reflector. This report calculates the phase center of an offset-fed dish reflector antenna.
