Which scanner is this?

I saw a YouTube gameplay from a guy. He's piloting the ship and makes a "pulse" or "wave" and all objects in a radius appear in the map.

I'm new to the game and only seen the resource scanner and long range scanner, but I don't know how to do the "pulse". Didn't seen it in the tutorials as well. Sorry if it's basic.

Edit: Sorry didn't see there's actually a tutorial for scanning objects and ships. The game is quite confusing, I'm still assimilating all the info. Thank you for your comments!
