An over-the-horizon potential safety threat vehicle identification method based on ETC big data [PDF]

Heliyon, 2023
Smart cars rely on sensors like LIDAR and high-precision map-based perception for driving environment sensing. However, they can't detect low-speed vehicles beyond visual range, affecting safety and comfort. Manual vehicles face similar challenges.

Experimental Analysis of Atmospheric Ducts and Navigation Radar Over-the-Horizon Detection

Remote Sensing, 2022
Since the height of sea detection radar antenna and ship targets is relatively low, it is generally believed that its over-the-horizon detection is mainly caused by the evaporation duct at sea.

Dynamic Identification Method for Potential Threat Vehicles beyond Line of Sight in Expressway Scenarios

Applied Sciences, 2023
Due to the challenge of limited line of sight in the perception system of intelligent driving vehicles (cameras, radar, body sensors, etc.), which can only perceive threats within a limited range, potential threats outside the line of sight cannot be fed
