| 摘 要： | 工程上常用静态RCS数据作为建立起伏目标回波信号模型的样本，其准确性和合理性亟待验证。文中基于空气动力原理提出了一种动态RCS特性的仿真方法，获取了F-117A型隐身攻击机侧站盘旋一周的动态数据。从统计特征参数、相关特性和起伏模型等方面对比了动静态RCS特性。着重分析了动静态RCS特性在起伏目标检测性能评估上的差异。结果表明静态RCS特性难以反映目标运动时真实的雷达特性，利用静态数据描述目标特性可能导致错误结论。

| Abstract: | The static RCS data is usually used for establishing fluctuating targets’ echo model in engineering, the accuracy and rationality of it urgently need verification. A simulation method for dynamic RCS data was proposed in this paper according to aerodynamic theory and the dynamic data of F-117A stealthy attacker’s spiral flying was acquired. Two kinds of data were compared on statistical parameters, correlation characteristics and fluctuating model. The differences between dynamic and static RCS characteristics on evaluation of fluctuating targets’ detection ability were analyzed. The results show that it’s hard for static data to reflect true radar characteristics when target is moving, using static data to describe target characteristics may lead false conclusion. |
