Calibration on X-band radar ranging with laser lidar

Abstract

Radar plays a crucial role in the detection of ships, structures, drones, etc. For offshore vessels, radar is installed on the top of the ships to observe their position and the land for contact accidents and defense applications such as the Aegis system. However, the accuracy of radar position detection is limited by the uncertainty of the radar calibration. In this study, we demonstrate the determination of the position of an island with high accuracy using laser-based light detection and ranging by measuring the distance and using it as a reference distance.
