[ONE ITEM PER REPORT] TWS and other Radar issues

[Beamscanner]

L&S/DT2 ageout does not match ageout of ranked track files ( 1 - 8 ).

Put L&S/DT2 tracks at the edge of a TWS sweep and you'll see that they dim out before the radars even gotten back to revisit them. Dim should only occur when a revisit results in no detection.

 

TWS "Hits" are extrapolated.

"Hits" and bricks should not be extrapolated. ie they should not have predicted movement like trackfiles.

 

Interleaved PRF mode does not invert after each frame.

In order to properly scan all elevations with both HPRF and MPRF, the radar switches the order of its waveforms.

 

Example:

4 Bar scan

Frame 1 - Bar 1 = HPRF

Frame 1 - Bar 2 = MPRF

Frame 1 - Bar 3 = HPRF

Frame 1 - Bar 4 = MPRF

 

Frame 2 - Bar 1 = MPRF

Frame 2 - Bar 2 = HPRF

Frame 2 - Bar 3 = MPRF

Frame 2 - Bar 4 = HPRF

 

etc..

 

RWR trackfiles on radar display should be just below the angle only dugout.

Just below the dugout, not inside the dugout.

 

RWR trackfiles on the radar display should be layered by priority.

Currently they have illegible overlap. #1 priority RWR track should be on top and legible.

 

"Angle Only Dugout" should not have range based contacts (ie Hits or trackfiles)

max range of radar should end just below the dugout.

 

Raid Scan does not function properly.

RAID scan is not used to zoom in on closely spaced trackfiles. (thats what EXP is for) RAID is used on a single trackfile to see if that one trackfile is actually two (or more) aircraft in close proximity sharing a very close doppler. RAID scan will center the screen on the trackfile and populate Hits behind it in a range vs doppler display (X axis = doppler, Y axis = range). The pilot then monitors the path of the Hits to see if there are two or more linear paths indicating two or more aircraft within the beam.

L&S/DT2 trackfile icons appear below the LAR icons on the radar display.

 

TWS azmiuth slewing offsets the RWS scan area when switched back.

 

Undesignate button, when placed over a L&S or DT2, will not drop the designation.

"Manual undesignate" occurs when the cursor is placed over a trackfile. This drops whatever designation the contact had.

 

 

RWS Manual undesignate = L&S -> Brick

TWS Manual undesignate = L&S -> Ranked Trackfile

Great stuff

[bkthunder]

Wow, didn't know that much stuff was not accurate in the F-18 radar.

Thanks for the in-depth explanation and hopefully the devs can chime in on this list!

did anyone notice hornet's TWS scan (or lock) doesn't produce any kind of nails in other plane's RWRs ?

[Krippz]

Good bug report.

Great summary. Most of that was reported long time ago, but no fix so far.
