Abstract: Working principle and research progress of oil spill information extraction and analysis from marine radar sea clutter is expounded firstly. And work flow and architecture of oil spill information acquisition and analysis model is put forward based on SPx, OpenCV, MatLab technologies and HPx marine radar signal collecting card. Oil spill information acquisition and analysis model is established by C++. And combined with the actual case of Dalian 716 oil spill incident, its effectiveness is verified. Based on the original navigation function, original signal is converted to realize marine oil spill monitoring function synchronously. It can provide the data base for the oil spill monitoring and early warning, oil spill track back and oil spill emergency disposal.
