Passive Ranging and Deghosting
_________________________________________________________________
Currently, ships must achieve burnthru on jammers in order to engage,
either by waiting until the jammer has approached closely or by
expending additional time and energy in burnthru. CEC allows the ships
to form a composite track on the jammers based on passive angle track
data from each of the ships.
Passive angle track data on the jammers is distributed by the CEC net.
Elevation and azimuth data are combined by a CEC
triangulation/deghosting algorithm to provide a fire control quality
track on each of the jammers. The ships can then engage the jammers
using the CEC composite track at much greater ranges without the need
to achieve burnthru.

A deghosting feature removes the "ghost" tracks formed where the
passive angle tracks from the different ships cross.
