Two-Dimensional Ship Velocity Retrieval from the Kompsat-5 SAR
IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019This paper presents a method and application results of two-dimensional ship velocity retrieval from KOMPSAT-5 X-band SAR via Doppler parameter estimation. It is necessary to estimate both range and azimuth velocity in order to restore the information of heading and velocity of ships in coastal area.

KOMPSAT-5 spotlight SAR processor using FSA with calculation of effective velocity
2010 IEEE International Geoscience and Remote Sensing Symposium, 2010In KOMPSAT-5 program, Korea Aerospace Research Institute has made SAR imaging chain analysis tool to evaluate imaging system of KOMPSAT-5. The tool consists of a simulator and a processor. The simulator simulates observation of a scene by the operational mode of KOMPSAT-5 and generates SAR raw data. The processor generates an image of the scene.

Bias assessment of sea ice concentration (SIC) derived from passive microwave sensors is very important because it has been used as an important parameter for climate change research. In this study, we analyzed biases in SICs retrieved from NASA Team (NT) and Arctic Radiation and Turbulence Interaction STudy (ARTIST) Sea Ice (ASI) algorithm implemented
