"WebFor that reason many RADAR’s in use for obstacle detection will be “high frequency” so that the wavelength is shorter (hence why we often use mm-wave in robotics) and can detect smaller objects." This does provide some intuitive understanding as to why devices emitting higher frequency signals provide high-resolution data. " - Hih frequency radars
