And more in general stands for Active Electronically Scanned Array,
which is the name for the type of antenna/emitter group. Instead of a
mechanically swivelling antenna (with complicated waveguides and a heavy
hydraulic system to move it around) this has a flat, fixed array
consisting of multiple emitter/receiver modules. The beam is controlled
electronically and at least in theory such a radar can use multiple
modes simultaneously. In the F/A-18F (with the ACS) this could mean that
for instance the pilot would have an air-to-air mode selected, while the
NFO in the back could be using a ground-mapping mode at the same time.

Is this the phased array radar?
And if not,wthat's the difference?
