Suggestion to improve radar mechanics in the game.
Just use the formula.
This will allow you to customize values for every vehicle.
Examples:
If possible, adding Doppler effect will make it more realistic.
Also to use this feature you will need to decrease all real values of vehicles in proportion to decreased radar distance value. Radar distances could be customizable as well, to simulate using different types of radars (witch can depend on types of vehicles to make it easier)
You need something to avoid unrealistic values for community content.
"Just use the formula"
Not that easy without further infos. What does Ps, G, Lamda, Sigma and Pe stands for.
