GMTI Standards OWS-8 Information Model for Moving Target Indicators and Moving Object Bookmarks (Engineering Report)
NSIF, STANAG 4545 or the National Imagery Transmission Format NITF, MIL- STD-2500 for the dissemination of secondary imagery, or in a message- oriented
format such as the NATO Primary Imagery Format STANAG 7023 for the dissemination of primary imagery.Those formats can embed usually by reference
GMTI data, but not vice versa.
The following diagram illustrates the typical data flow from sensor systems to exploitation systems and shows where GMTIF is usually used. The sensor system
provides “typically a digitized video signal, such as I and Q data, and is not suitable for transmission using the GMTI format” Nato2008. The IQ data contain pre-
spectral in-phase I and quadrature Q radar return samples, which are both required for Doppler spectral calculation.
From on the detection system onwards, GMTIF is used. Initial detection systems can transfer the data optionally to additional processing systems or directly to exploitation
systems.Exploitation Systems include: “Trackers, situational awareness displays, evidence accumulators, automatic target recognition ATR, fusion or correlation
with other sensor data, and other systems that exploit GMTI data. Note that the GMTI Format is intended to provide the detections and the supporting information needed
by those exploitation systems; it is not intended to provide a format for exploitation products.” Nato2008

In general, GMTI data is used at various direct links between systems. Data links for over the air transmissions may be used. The following diagram illustrates the usage
of GMTIF within different systems and platforms.
