一种基于DEM的雷达地形遮蔽盲区确定方法
Method for Determination of Radar Terrain Masking Blind Zone Based on DEM
摘要
Abstract
Aimed at the problem that the conventional tracking the flight by radar is demanding and hard to control overall, this paper puts forward a method for computation of radar terrain masking blind zone by taking up the digital elevation model (DEM). In this scheme, the surface elevation data from various azimuth range of the radar can be converted to its observation elevation, the terrain masking point be pinned up to form the masking section of radar azimuth terrain, in comparison with the perpendicular power pattern of radars’free space. And then all those sections form the terrain masking blind zone of the radar, thus determining the radar’s detection power range at various altitude levels. Simulation results show that this proposed method can be used for more comprehensive and accurate map of radar detection power by combining radars’tracking the flight, thus offering a reliable basis of radar detection power range for the deployment and defensive operation of radar.关键词
