Radio Acoustic Ranging (RAR) is a method used to determine the distance to an object by using both radio waves and acoustic waves. This technique leverages the different propagation characteristics of these two types of waves in various mediums, typically in marine or underwater environments. \#\#\# How It Works: 1. **Signal Generation**: An acoustic source emits a sound wave (usually a low-frequency pulse).
