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.

Pointing accuracy of airborne multi-light source steering device

“…The airborne infrared steering device has found widespread application in modern opto-mechanical systems owing to its strong anti-interference ability, long working distance, and high measurement accuracy [1,2,3,4,5,6]. With the rapid development of modern science and technology, higher requirements have been proposed for its performance, leading to the emergence of multi-light source steering devices.…”
