| Principles of Interferometry |
| This is known as a connected-element array, | ||
| Baseline B: | ||
| Distance between antennas. | ||
| ÒVirtualÓ telescope of diameter: | ||
| B.cosθ (projected baseline) | ||
| Fringe pattern provides information on structure and position of the radio source. | ||

| remote operation, | ||
| focal-plane arrays, | ||
| computing challenges. | ||
| Useful astronomical instrument in its own right. | ||
| Funded: A$100.9m. | ||
| Around 30 × 12m antennas located near Boolardy station in Western Australia. | ||
| Smaller 6 antenna ÒoutpostÓ in NSW. | ||
