Research On Marine Radar Simulator Echo Image Based On Modeling And Simulation Technology Of Radar Sensor

The marine radar simulator is very important for improving the navigator’s ability of radar navigation,reducing marine accidents and saving maritime training cost. Though the marine radar simulator develops gradually, we must recoginise that we have many work to do in improving the physical realism and behavioral realism.System modeling and simulation technology play an important role in many fields,however,it’s not well applied in simulation of marine radar echo image.Many researchers do lots of work in the radar image simulation, these efforts improve radar echo image’s quality to some extent. However, these methods didn’t take well the radar antenna beam width and directivity diagram in consideration, which also lead to the differences between radar simulator’s echo images and real images.Most previous radar simulators were based on the the scan line simulation, the technical specifications of the transceiver and antenna (radar sensors) were not well considered in the simulation. Radar sensors include radar transceiver and radar antenna, and the most important equipment parameters for the radar observation is technical specifications of the radar antenna.The main goal of this subject is to build marine radar echo simulation image based on system modeling and simulation technology of radar sensors. In this paper, The key work involves:1.By learning theory of system modeling and simulation technology and the radar sensors, establish a mathematical model of the radar sensor;2. According to the research and study of the propagation characteristics of the radar waves and radar targets,establish electromagnetic models of radar targets and maturity models of radar clutter;3.According to the mathematical models of the radar sensors, the radar targets and radar clutter, simulate the radar echo image.
