investigating GMT INTL

[Beamscanner]

While operating GMT with INTL selected. In this mode, the radar performs ground mapping (a) and ground moving target detection (b) on an interleaved basis, alternating with the sweep of the search pattern.

 

For instance, when sweeping right, the radar performs GMT. When sweeping left, the radar performs ground mapping. 

 

Issue: 

Data from sweep "a" does not persist while performing sweep "b". Just like the DCS F-16's GM/GMT INTL mode, data from sweep "a" should not be removed until the next sweep "a" is updates. Same goes for data from sweep "b".

 

The intended effect: GMTs overlaid on top of map. (same as DCS F-16) 

 

Current effect: sliding door effect of data, where you cant easily make out or interpret landscape around a GMT.

I presume it should be the same for SEA as well...

Oh look, the APG-70 also made by Hughes/Raytheon, has a RBGM / GMT INTL mode with overlaid data, (both the map and GMT) rather than a sliding screen door of one set of data at a time. 

 

And ED wonders why the community doesn't think the DCS F/A-18C was done well.
