摘要
动态测量是获取飞机电磁散射特性的一个必要手段,由于飞机飞行时姿态变化及背景等因素的影响,RCS动态测量数据呈现出剧烈的起伏。本文首先分析了离散数据统计建模与参数获取的方法,然后就某型号目标的RCS数据,应用理论模型对其进行拟合,得到其典型视向RCS的近似分布规律。
Dynamic measurement is necessary for getting a plane抯 scattering characteristics, for reasons of change of plane抯 the gesture in flight at all time and background effect, etc, the radar cross section (RCS) measurement data appear as an quick fluctuating. In this paper, the method of obtainable parameter and disperse data statistical modeling are analyzed first, then the theory model is fitted to the RCS data of a type of the target from which is obtained the approximate distributed rule of the typical and apparent RCS. At last, the data fitting error is calculated and analyzed.
