I'd like to see in-game options to adjust the scaling of these 4 things without having to dig through the code every time the mod updates. It's a good mod, but it's way too strong by default in my opinion. Power drain should ramp up more, and the sectors should really only increase by about 1 and 2 respectively. The scanning speed bonus should also be about halved, since less sectors to scan, and much less UPS hit.

Increases the speed at which radars scan distant sectors
Increases the range (radius) of nearby revealed sectors by 2 each upgrade
Increases the range (radius) of distant sectors by 3 each upgrade
Increases Radar power requirements by 75KW

I agree whole-heatedly with you, came here to post a similar request. I love the faster scan rate but the huge revealed sectors increase makes having a radar at every mining outpost absolutely overkill. Please offer us a way to configure them to our liking from in-game!
