Great work. Had the same idea, but wasn't confident I could replicate the cool sonar effect you made, so I went in a different direction. Would you mind divulging how you went about it?
I did alot of searching forums and youtube on echolocation and found a few relevent YouTube videos and adapted them to suit my needs for my game, one of the videos was a shader study on the radar effect from no mans sky and another was a pulsing radar effect
