Analysis of accuracy of surveillance radar image overlay by using georeferencing method

Shore-based radars are the key element of vessel traffic management systems, such as the VTS. To present a true visualisation of the environment and location of radar-detected targets, a radar image needs appropriate calibration. The image itself may be subject to various distortions, including systemic ones. This paper presents a study of usefulness of various georeferencing methods in the determination of radar image distortions and assessment of the accuracy of surveillance radar image overlay.
