what means passive and active scan?
A passive scan just looks at any incoming signals, like looking at light through a telescope.
An active scan sends out a signal and looks for what bounces back, like radar.

The most merciful thing in the world, I think, is the inability of the
human mind to correlate all of its contents. We live on a placid
island of ignorance in the midst of black seas of infinity, and it was
not meant that we should go far. -- HP Lovecraft, "The Call of Cthulhu"
