[INLINE] 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] [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] _________________________________________________________________ [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.
