| 摘 要： | 针对雷达作用范围二维表现方式的不足,提出了一种基于混合采样的雷达作用范围三维建模方法。以雷达方程为基础,通过地形分辨率网格确定雷达方位角方向的采样步长,使雷达模型对不同精度地形具有自适应性。以雷达的3dB特征点为基准,对雷达俯仰角进行分区域采样,在保证模型外形与雷达特征属性一致的同时有效减少了绘制点的数目。实验结果表明,基于混合采样的三维建模方法不仅能快速、准确完成雷达三维建模,而且能更加直观地展现雷达探测范围。

| Abstract: | In view of the deficiency of two-dimensional expression of the radar coverage, a hybrid sampling method for the modeling of radar coverage is presented. Based on the radar equation, the radar azimuth sampling step is determined by the resolution of terrain, so that the radar model has self-adaptability to different terrain resolution. Use the 3dB feature points as the base of the pitching angle for the sub-area sampling, in ensuring the model shape consistent with the properties of radar, while effectively ... |
