CEC Operations
_________________________________________________________________
CEC brings revolutionary new capability to air defense, not by adding
new radars or weapon systems, but by distributing sensor and weapons
data from existing systems in a new and significantly different
manner. This new capability brings significant benefits in all air
defense areas, including quantum improvements in track accuracy,
continuity, and ID consistency; provision of an identical picture to
all CEC units; and increased battle space, reduced reaction time, and
extended engagement ranges through cooperative engagements.
Sensor Cooperation
_________________________________________________________________
Without CEC, the Battle Group ships detect the target at different
times due to horizon limitations, multipath, and jamming. Their tracks
consequently start and stop at different times and have different
track numbers.
_________________________________________________________________
With CEC, data from each unit is distributed to all other units,
filtered, and combined using identical algorithms into a single common
air picture. [INLINE]

_________________________________________________________________
Each CU combines ownship radar measurement data with that from all the
other CEC Units using the same CEC algorithms. The result is an air
picture based on all the data available (thus superior to that of any
single sensor), providing the same tracks with the same track numbers
throughout the net.
Data Distribution
_________________________________________________________________
CEC distributes radar measurement data (not tracks) from each CU to
all other CUs. Units communicate in pairs during short
transmit/receive periods through a narrow directional signal. Data is
thus sent across the net in near real time and communication is
virtually jam-proof. [INLINE]

Engage On Remote
_________________________________________________________________
CEC units are able to engage on the basis of CEC composite tracks,
even when the firing unit does not hold the track, because CEC
provides precision gridlock and fire control quality tracks. The CEC
picture below shows USS Cape St. George conducting a remote engagement
using CEC data from USS Anzio during DT-IIA testing in mid-1994. The
solid line connects the target to the firing ship; the dotted line
connects the target with the ship providing the remote data. The fine
lines connecting the CUs show CEC net connectivity.
