I think we can hack this a bit. I have never worked on a radar map, but if it supports scaling, we can increase it when we create it in accordance with our requirements. Again, you should check this out, I'm not sure if this will work. This is just an idea. If you did it your own way, please let me know.
Scaling (software)
zoomIn(): 1.4f, .
zoomOut(): 0.7f, .
zoom (float scaleX, float scaleY, float x, float y): . x y - ( ) . , 1f = .
zoom (float scaleX, float scaleY, float xValue, float yValue, AxisDependency): . xValue yValue ( ) . , 1f = .
