摘要
飞行器隐身技术是当代军事技术中的一项重大突破,低雷达散射截面(RCS)的飞行器外形是专业人员努力追寻的研究目标。本文采用Toplitz变换和混合迭代的算法,对新设计的一种鸭式布局翼身融合体飞行器外形进行了RCS计算,并在微波暗室内对模型进行了测试。实验结果与理论值基本吻合,误差在1dB之内,证明此算法行之有效,优化设计的翼身融合体飞行器具有良好的隐身性能。
The stealth technology for the aircraft is an important break-through in military affairs. It needs more perfect electromagnetic scattering characteristics of the pilotless aircraft. This paper uses an algorithm for the Toplitz transformation and mixed-iteration for calculating the RCS for the blended wing body aircraft with a duck-liked overall arrangement. The models are tested in an anechoic chamber. Experimental results agree well with the numerical analysis. It proves that the algorithm is effective and the blended wing body aircraft is of good stealth characteristics.
