New options for the M2k?

Hi @ all,

after a long time I reactivated the M2k. I noticed the following in the options:

How long have these settings existed? And above all: what do they do? I would like to deal more with the module again over the coming holidays and finally tackle its campaigns

Okay, found something:

But I still don't know what modificator for radar TDC in PPI mode and TDC moves in polar coordinates mean. What a function lies behind it.

Polar coordinates means that you are moving TDC in angle and range in PPI mode.

If you set the TDC at 20Nm, and move it left to right or the opposite, the TDC will make an arc of circle. It was previously like that in PPI and X/ Y in B scope.

 

But IRL, it doesn't move like that, it moves in X/ Y mode (top/ bottom & left/ right).

So they make it happen in PPI display mode too.

 

But it seems that the TDC is struggling to lock target in PPI mode when you get far from center line.

So the TDC gate aperture is there to customize a circle around the TDC to lock the target, to compensate situation where you would put TDC on target and it wouldn't lock.

It seems that there is a problem translating X/ Y coordinates on PPI display.

Ahh ok Thanks. Now I realize I.e. Razbam only added this because of this issue: Kate promised to personally deal with the Mirage's radar problem: https://forums.eagle.ru/topic/231000-ed-issue-mirage-2000-antenna-elevation-bug-tdc-innacuracy-in-ppi/
