In: Lee, J.L.; Yoon, J.-S.; Cho, W.C.; Muin, M., and Lee, J. (eds.), The 3rd International Water Safety Symposium. Journal of Coastal Research, Special Issue No. 91, pp. 376-380. Coconut Creek (Florida), ISSN 0749-0208.This paper described the system test including from ground test to the first flight of Seahawk system in Korea. Seahawk system has been developed since 2014 at the first time in Korea by Ministry of Oceans and Fisheries. Seahawk has been recently integrated and system shakedown testing (on the ground). Airborne engineering flight test was in the first of June and flight test in Korea was in first of July. Seahawk system features a light weight, compact opto-mechanical design and achieves co-registered green and IR laser beams using a novel HOE (Holographic Optical Element) circular scanner. The Real Time Computation Engine (RTCE) displays 3D point clouds on the monitor in real time during operation to check missing data. In this paper, we introduce Seahawk system and report on the progress of its development.
