Multi-Node Support
The same target monitoring limits (CPA/TCPA, bow crossing) are applied
on all nodes in the system. These values are calculated on individual
displays so that a target may, for example, have a different CPA/TCPA on
each display, depending on the results from the target tracker.
Each node evaluates the alert conditions on the targets that have been
processed by that node. Whenever a target alert is acknowledged on a
node, all targets of the same number on other nodes will have their alert
condition acknowledged. If other nodes have f alerts or targets not present
on the acknowledging node, the alert condition for these targets remain
unchanged.
