Abstract
When off-road vehicles engage in water wading, the environment often contains high concentrations of suspended sediments (mud, silt, sand) that render the water entirely opaque. This completely obscures the underlying sub-surface topography and potential hazards, such as rocks or sinkholes. While current Advanced Driver-Assistance Systems (ADAS) are designed for standard road environments, optical cameras and LiDAR are face physical limitations when attempting to penetrate turbid or opaque water. Standard automotive radar (e.g., 77 GHz) operates at high frequencies that cannot penetrate dense, conductive liquid mediums. Furthermore, ultrasonic sensors only measure the vertical distance to the water's surface and lack forward-looking predictive capabilities.
