BAE EWACS ABM Radar

[JFC Fuller]

From the early 2000s (announced 2001), this one used MESAR technology, I assume its the end result of the notional ABM configurations mentioned here.

Les Gregory, BAe Land & Sea Systems head of business development, says MESAR 2 has 10W transmit/receive modules - 1,264 of them - while MESAR 1 had 156 modules rated at 2W. Modules are grouped in sets of four which form line replaceable units. Despite the number of heat-generating electronic components, BAe retains air cooling of the array, rather than resorting to more complex and costly liquid cooling. MESAR 2 is instrumented to 400km (215nm) range and 90í elevation.

Gregory says an operational BMD radar would have "3,000, 4,000, 5,000 and 10,000 module versions". Radars with fewer modules stop scanning if the array "stares" at a target. Having more modules allows scanning to continue while part of the array locks on to the target, he adds.

I am guessing that the numbers after EWACS refer to the number of modules...?
