Radar Detection Debate

Commenters debate the effectiveness, limitations, and applications of radar technology for object detection, often comparing it to lidar and questioning why it's not used more in scenarios like stealth evasion or collision avoidance.

Probably was a radar, not a lidar.

You need radar to detect incoming things anyway, and radar can be re-used.

Including their radar signatures?

Why can't we just shine some radar out there?

this isn't a radar-only phenomenon. such a hack would need to involve fooling human senses, visual, and radar.

Doesn't radar already do that? Without all the impracticalities of this approach?

Radar is not sufficient for mitigating this scenario. Too low resolution.

This rather sounds like radar is the wrong choice, does it not?

Forget the paint, how does the radar miss this??

I wonder how well it absorbs radar.
