APG-68 (time 4:49)

Notice the smooth and continuous trackfile extrapolation on the targets. Even the one leaving the radars scan volume on the bottom left of the display continues to be extrapolated and doesn't fade out after 4 seconds (>.>).. Hope this logic makes its way into DCS radar logic...

So I understand and to make it clear, you want ED to model a late 1980 block 25 radar for the USAF Block 50 circa 2007?

No. He didn’t say that. He wants ED to model radars more realistically across the board and that video just happens to show one thing that ED haven’t got right yet.

I will PM you since this seems beyond the scope of this thread

No..?

I want proper radar logic built into the latest iteration of ED modules. Some of the recent ED 4th gen modules lack said logic...

tried PM Deano87, but he just told me to PM you. What does the video show that is not modeled correctly in DCS?

Keeping in mind the video does not tell us if it is on the actual aircraft or a demo, or a simulator. It does not show the version of the APG-68, what software is on the aircraft, what updates to the radar, what years was it recorded, what country is that from, etc.

I tried similar scenario in DCS with the F-15, seven targets at 80+ miles same altitude, first one/closest being soft lock in TWS. DCS showed the exact behavior as in the video as far as I can tell.

If you read my initial post entirely you'll see that I mention what was lacking in DCS. Target extrapolation. Meaning the radar continues to predict target motion between radar revisits based on known target parameters (vector velocity, altitude, range, etc). Target extrapolation is the primary reason there is a limit to how many targets a radar can 'track'.

In the video you can see that the trackfiles continue to move smoothly between antenna revisits. The when the radar does make it back to the trackfile, the position is updated with the targets true position. As the radar moves off, the position is extrapolated again until the radar gets another visit.

This logic is not present in ED modules yet. The hornet does not yet perform target extrapolation though it should be doing this in LTWS RWS. As per the manual, the radar can track up to 10 targets in RWS/TWS.

Many other features are missing in ED modules as well.

Just to name a few:

-Closely spaced targets being detected as one target
-Accurate trackfile ageout
-Altitude notch (Heatblur actually has this modeled in the F-14, but not ED)
-Doppler notch off in look-up conditions (again, Heatblur has modeled this)
-Unassociated radar hits. (you can actually see this in the APG-68 video I posted, but if a "brick" is too far from a trackfile or doesn't line up with the trackfiles projected path, the brick wont be properly associated/coorelated to the trackfile. And thus you'll see a 'random' brick pop in once in awhile. In truth, it is probably a hit of the target with parameters that didnt quite meet the criteria for trackfile association. For instance, if it was a large target, your sidelobes could have detected the target again at the same range but offset left or right of the trackfile.
