摘要: 雷达散射目标特性(RCS)是无人直升机的重要性能指标。以某型直升机几何参数为例,分析了无人直升机RCS的特点,基于CAD软件法和电磁计算网格法建立其几何模型并生成了机身旋翼电磁计算网格。在编制计算分析流程基础上,分析计算了无人直升机RCS性能指标,得出了无人直升机的RCS分析结果。

Abstract: Radar scattering characteristics of target is an important performance index of unmanned helicopter. With a certain type of helicopter geometric parameters as an example, analyzes the characteristics of unmanned helicopter RCS, establishes the geometric model and computes the fuselage and rotor electromagnetic grid based on CAD software and rotor electromagnetic grid method. Through making calculation and analysis process, analyzes unmanned helicopter RCS performance index and obtains the RCS analysis results of unmanned helicopter.
