Simulation and analysis system of sea echo based on MATLAB

Abstract

Marine radar is mainly used for maritime navigation and avoidance of collision. Shore-based marine radar is used for offshore vessel management. In the marine environment, the radar echo is complex for the targets which are polytypic and undulant, and the clutter is strongly and violently affected by the environment. In order to simulate and analyse the sea echo from shore-based radar with real time and high precision, this study sets up a kind of MATLAB simulation and analyses system of real-time data communication and record playback based on transport control protocol/ Internet protocol and GUI. The system can realise the multi-dimensional multi-mode display and subsequent refined simulation of the echo based on static data or dynamic data, and the situation analysis of marine environment is provided through the learning training of multi-frame data. The system has been successfully applied in field experiments and has played an important role in fault analysis and algorithm optimisation, which has very high application value.
