一种复杂场景雷达图像实时仿真方法

雷达图像计算机仿真技术是解决多参数雷达图像数据源匮乏的有效途径,其核心是对地表场景电磁物理模型的建模.文中提出了一种利用待仿真场景地物的先验信息和数字高程信息,对待仿真场景进行雷达成像的电磁物理特性建模,进而实现雷达图像仿真的方法.仿真结果表明,该方法可以实时地对地表复杂大场景进行多模式、多参数变化的雷达成像仿真.

A Real-time Simulation Method of Complex Scene Radar Images

The technology of computer radar image simulation is an efficient way to solve the problem of insufficiency of radar images.The difficulty of the problem is mainly caused by the electromagnetic modeling of the objects.A new electromagnetic modeling method based on the terrain and geometry a priori information of the scene to be simulated is introduced in this paper.The validity of the simulation method is proved by simultaneous simulation of different kinds of radar imaging modes and multiparameters using t...
