The 53 EWG's commitment to review known threat systems in the EWIRDB, USELMS, through the FME program, and to update and validate the MD in the more than 30 EW systems prior to OEF and OIF was critical to aircrew EW combat survivability.
Data in the EWIRDB are gathered either by observation or assessment.
By comparing the emitter parameters of an unknown threat to those cataloged in the EWIRDB, an EW operator can identify the source as one which has been previously encountered or an unknown.
But as the members of the EWIRDB grew, the computing power required to make the correlation between an observed signal and a cataloged emitter in a timely fashion also grew.
