Abstract

Abstract:

Sea clutter is the main factor affecting the radar target detection, but the marine atmospheric environment changes the sea clutter characteristics by influencing the electromagnetic wave propagation path. The cause of sea clutter characteristic difference is analyzed in the different atmospheric environments, and the empirical model is used to establish an algorithm of sea clutter characteristic quantity based on the "opposite distance" method. The real sea clutter characteristics are simulated with the experiment data in Ref. [9]. It is found from the comparison of the datum observed in four directions that the simulation value is agreement with the measured average value. Finally, the sea clutter characteristics in standard atmosphere, evaporation duct and surface duct environment are investigated by using the simulative environment conditions and radar parameters. And the results show that, compared with the standard atmosphere environment, the sea clutter characteristics show a trend of increase in the duct environment, and the first skip zone in the surface duct environment also presents weak clutter or no clutter.

Key words: radar engineering, marine atmospheric environment, sea clutter characteristic, opposite distance method
