Modeling and simulation of airborne radar clutter in a littoral complex environment

Facing increasingly severe electromagnetic environment of complex coastal background, the capability of airborne radar for target detection and tracking is influenced seriously. So it is of great significance to study the modeling and simulation of the airborne radar clutter in coastal environment. Based on the coastal environment scattering theory, the compound clutter generation principle in coastal area is first explored and then the back scattering coefficient model of coastal clutter is established in this paper. Finally, the clutter power spectrum calculation of airborne PD radar around coastal environment is explored combining with the digital elevation model (DEM). Simulation results show that the model of compound clutter in coastal area and its power spectrum calculation are effective and practical.
