This sensor system includes hi-res video sensors, hi-fidelity audio sensors, a chemical vapor scanner, pressure sensors, and either a ladar or sonar system. Ladar uses laser detectors and ranging sensors to rapidly play low-powered laser beams across your surroundings, allowing you to locate targets. Sonar sensors are used mostly in subaquatic environments, but the technology works almost as well in the air. By bouncing sound waves off objects and measuring the length of time it takes to receive an echo, sonar can produce a clear image of your surroundings.
