摘　　要：在飞行器同雷达对抗时的不同威胁情况下,分析了在雷达仰视照射下飞行器的隐身性能。通过绘制雷达仰角图,得到了目标飞行器在某典型雷达照射下的暴露与隐身区域,从而量化了目标飞行器的隐身性能。通过CATIA二次开发技术实现了CAD模型的便捷修改,为优化外形隐身特性提供支持。最后通过一个具体算例验证种方法的效果,并说明方法具有实用意义。Under the threat of confrontation of the aircraft with radar, this paper analyzes the stealth per- formances of the aircraft under the radar looking up. By plotting the radar elevation map, we got the ex- posed and stealth regions of a target aircraft irradiated to typical radar, thus quantifying the stealth per- formances of the target aircraft. CATIA secondary development technology has simplified the modification of the CAD model, providing supports to optimize the characteristics of shape stealth. At the end of this paper, a specific example has been applied to verify the effect of this method, and illustrate practical sig- nificance of this method.
