Today ground moving target AG radar mode has been introduced. As far as I understand this mode can be used by facing radar towards to the targets Wereas normal exp modes can not. We need to approach with a particular angle. Are those different devices that work with different techs?

Both GMT and DBS/SAR use the same radar transmitter, receiver, and antenna, it's the way in which the signal is processed which is different. 

 

GMT works in much the same way as the A/A radar does: it uses Doppler shift filtering to distinguish moving targets from the background. 

 

The DBS/SAR modes use an algorithm to analyze the way radar returns shift as the angle of an object changes relative to the radar's path of motion to increase the effective angular resolution of a radar map. Because the angle to an object directly ahead of the radar will never change as you fly towards it, this method of processing only works at an oblique angle to either side.

In regard to GMT, I'm wondering:

1) Will it be able to detect low flying helos?

2) Can ground vehicles notch it by driving at a 90° angle?

DCS Panavia Tornado (IDS) really needs to be a thing!

Does the SEA mode requires the ship to be moving in order to show a brick?

 

I know GMT does with vehicles but I'm not sure about SEA.

 

 

THanks.

No, SEA mode filters targets from a baseline water/sea return, generating synthetic bricks even on static targets.

GMT/SEA interleaved with RBGM (ground mapping) looks to have an issue. 

 

Theyre correct in that the mode changes with each scan.. (ie scan right = GMT, scan left = Mapping)

 

But the data shouldn't be erased when the mode switches. 

 

For instance, the map data should be frozen in the background when the GMT sweep is happening (not erased); and then updated when the mapping sweep occurs.

How is "Civil Traffic" interacting with the GMT mode?

 

I'm pretty sure that DCS does not count civ traffic as an actual "unit", which might make it undetectable by the radar, don't quote me on that tho, might be outdated info

Civil Traffic won't interact right now, basically the generated traffic right now is an effect more than a real unit. And to be honest, to show all those units might melt some computers. 

 

Down the road, we would like to add some civilian traffic as place-able units (some older ones already exist), and most likely those could be picked up by GMT mode, but as for now, no.
