you talk about others with a closed mind Disk
Who cares _ it's got nothing to do with the issue
Lets for argument sake, go back in time to when YWLM had raw (analogue) radar prior to the ADATS installation.

If your aircraft was correlated and displayed on the screen, it would have a blob containing the primary marker (blob) and the beacon slash (orientated perpendicular to an imaginary line drawn towards the radar head). Another aircraft also in the area would be displayed the same way.

If the relative width of the beacon slash was ... oh I don't know, say and average of 3nm close in to the field .... how far between aircraft positions (centre to centre) would Target Resolution bring them?

1.5 + 1.5 = 3nm .... Ah ha

Jump forward to modern day, Digital with small circular symbols on the controllers screen which are the same size (visually) no matter which screen scale is selected.

Also, let's asume the next election has been and gone .. beforehand, you had taken out paper adverts, got your face on telly and radio thanks to the blinky eyed uninformed media, and, dills like MRabbott and The Albo had said to you:-

"yes Disk, we will fix it for you (gobble gobble)"

And voila 'Target Resolution' is all systems go!

The normal screen range will have edge to edge a lot closer than the separation minima. If the controller zooms in to say 15nm range ... if target resolution was used with these systems, at a small scale setting, the aircraft could be as close as 500m apart.

Do you see the relevance???

As le Pingouin and others (including AsA and the FAA) have pointed out, this is why Target Resolution cannot and is not used with digital systems.
