3D visualization method on real-time division of radars mutual electromagnetic interference
In order to observe and analyze the space of mutual electromagnetic interference from different aspects and perspectives,this paper took advantage of the characteristics of the boundaries of the isosurface to divide the radars mutual electromagnetic interference space.It measured the degree of the radars mutual electromagnetic interference by energy flux density and interference margin in the warship formation.And it used a progressive grid sampling extremum octree to reconstruct the isosurface quickly.It employed the differential display mode of the isosurface to create a real-time interactive 3D chart with a top view,a front view and a side view,while displaying the simulation results of the radars mutual interference in the warship formation dynamically.This paper simulated 6 ships with 16 single-pulse radars to interfere each other.The result shows this method is feasible and effective.It can be applied to the real-time 3D visual simulation of the electromagnetic environment of the electromagnetic interference in the large scene.It can also be used in the 3D visual simulation of the UAV radar electromagnetic interference research and prevention.
