Which radar is noted for not being the only radar to detect air contact in 3D?

The radar known for not being the only radar to detect air contact in 3D is the Spy radar system. The Spy radar, designed for advanced air and missile defense, is capable of detecting three-dimensional air contacts and provides tracking information. However, it is important to recognize that there are other radar systems, such as some advanced surveillance radars and airborne detection systems, that also have the capability to detect air contacts in three dimensions. This characteristic makes the Spy radar a part of a wider group of radar systems with similar functionalities, rather than being unique in that capability.
