基于目标和地面电磁反射特性数据库的信息和雷达探测模型，实现了雷达图像动态生成。
By the use of the electromagnetic reflection information of targets and ground in database, the radar detection model can generate radar image dynamically.
首先用参数模型来描述雷达探测信号，然后用最大似然(ml)法对模型参数进行估计。
Using parameter model to describe the radar signals reflective from targets and then the model parameters are estimated by means of ML method.
该方法综合考虑真实环境因素的影响，采用了抛物方程方法，最后给出了雷达最大探测范围三维模型的建立和表现方法。
In this method, the effect of most real environment factors is considered with parabolic equation. Finally, the method of building and rendering 3d model of radar maximum detection range is given.
