雷达目标距离像分类机理的研究

A Study of the classification mechanism of Radar Target Range Profiles

文中用散射点模型的观点对雷达目标距离像的分类机理进行了探讨.首先从散射点模型出发导出距离像在近姿态角上强相关和在远姿态角上弱相关的距离像相关框架,指出这个框架只有在全姿态角范围采集足够多距离像构成模板链才能完备地确定刻划目标的识别特征.作者用实验数据对这个结论作了验证,并探讨了姿态角范围与识别率的数量关系.

The classification mechanism of radar target range profiles is investigated using the model of point scatters.First,the range profile correlation frame is derived directly from the point scatters model, which shows that only a set of range profile observations stepped in some completely small aspect increment can fully characterize the classification features of an object.Then,the range profile correlation frame is further proved experimentally,with the dependence of classification rate on the size of the aspect increment derived from the experimental results.
