Echolocation Material Effect

Hey there everyone,
I’ve been trying to achieve an Echolocation effect with Post Processing Material but I’ve been stuck. I’ve figured out how to get the effect to work but only with one location. I want to be able to have the effect work on many different locations.

Here is an example of how I want it to work and look like. I’ve also attached a picture of the material I’ve made so far.
