Radar Speed Gate

[Creampie]

Does anyone know if the speed gate is actually modeled in? Swapping it between H/L specifically in A2G GMTI seem to have no differences

[Creampie]

After doing some testing, it doesn't seem to change anything

Scenario;

I chose to use a heli because its the most consistent with speed & using GMTI for finding them works as intended

I ran 4 sets of tests. A head on, a 45 degree offset, a 90 degree offset & a rear aspect

(All tests started at 30nm and flew until 5nm) Altitude 2,000, Heli Altitude (scraping the floor lol)

150 KNTS; Can't be seen on H or L

140 KNTS; Can't be seen on H or L

130 KNTS; Can't be seen on H or L

125 KNTS; Can't be seen on H or L

120 KNTS; Can't be seen on H or L

118 KNTS; Can be seen on both H & L but only what seemed to be every other radar sweep

115 KNT; Can be seen on both H & L (and all speed lower than this)

In theory, The unit should be able to be spotted using H at speeds between 120knts & 150knts

Not sure if this needs to be put into bug reports or not.

I will continue testing them with the fastest CTLD units & other variations of helicopters later in the week and post them here 

 

Units to test;

CH47

CTLD Avenger;

CTLD Technical; 

Kiowa;

Apache;

Mi24;

Kiowa/Apache & Mi24 all share the same results on the above post;

CTLD all seem to be spotted via GMTI at max speed on both H & L.

 

The H should be displaying these helis going at the higher speeds but does not seem to be working?

Here's google translate of the manual from the docs:

The detection distance for ground moving vehicles is ≥20NM. Of course, as the name suggests, GMTI can only find moving targets. If the target stops, you can't do anything; the radar filter speed gate (low/high) can be set in the lower right corner of the radar MFD page. L (low speed) displays targets with a moving speed of more than 7 knots, and H (high speed) displays targets with a moving speed of more than 15 knots.

I was sent this by a friend on mine.

I wonder if they are talking standard JF measurements where as 1=10? So 7=70 & 15=150

I don't think the H/L would be 7 & 15, So 8mph & 17mph.

At that point it wouldn't even be a feature. In the real world or DCS

Detection of ground targets going above 70kts would make absolutely no sense because the only thing that would get detected, military wise, would be fast moving helicopters.

At 100+ kts I think you can already use A2A radar to pick up helicopters.

As to why there would be only 8kts difference between gates - no idea, maybe related to weapons.

You are correct about the A2A radar.

However the point of this is not to find helicopters as there is a multitude of ways to do exactly that. That inherently is just a benefit of it. 

Having a feature to highlight targets moving at jogging and running speed just not only seems like an absolute waste of resources, R&D and implementation to its actual platform. You could just use ground radar at that point, they're basically sitting still.

I can only assume that the intention of H/L, L being UP TO 70, H being UP TO 150... Obviously sheer speculation only because 7 & 15 knots just does not make sense. The average speed of a modern tank in just a traveling format is 30 knots/33mph/50(ish)kph

 

I don't know if I should put this in bug report because I just don't know if it is working as intended or not. It's really quite hard to say.
