The ATA is an array of many small dishes that can be combined to form the equivalent of a single large dish antenna. How this works is illustrated in the following diagrams based on originals by Dr.

Block diagram of a conventional radar system using a parabolic dish. In a phased array radar (PDF) system an array of antenna elements are used instead of the dish. These elements are phase ...

In addition, it is easy to expand an array by merely buying additional antennas and connecting them into the system. Single, large dish antennas are not amenable to such simple improvement. The bottom ...

We say sacrifice because [Kenneth] had to literally destroy the dish to get a look inside. It doesn’t appear that you can realistically get into the exceptionally thin antenna array without ...

Imagine taking the radio frequency properties of the dish antennas you see ... in Advanced Materials. Most RF antennas, particularly highly directional array antennas like reflectarrays are ...
