An article published in the May 2004 issue of the Navy League's Sea
Power Magazine says the USS Pinckney DDG-91 is the first Aegis ****p
that can transmit beams from two SPY-1 arrays at the same time.
"One of the most significant improvements is in the computer program.
For example, "dual-beaming" is a new feature that nearly doubles the
rate at which sailors can search the combat air space; it involves two
opposing array faces simultaneously sending out and processing pulses.
Previous generations of SPY-1 radars could only transmit from one array
face at a time."
Anybody know why four faces cannot transmit simultaneously? Is it
because of the limitation in the computer program as implied in the
article or the four arrays share a common transmitter?
