【摘要】 对雷达和导弹制导系统的设计师来说,隐身飞机的目标特征信号是诱人的。本文将提出一些新的隐身目标特征信号,它包括有低自由度的x~2统计分布模型,宽带频率特性,非线性谐波响应,极化本征值以及双基地散射等。隐身飞行器表面实施阻抗加载将增大目标角闪烁,并使目标成象畸变。部分仿真结果与理论估算相一致。更多还原

【Abstract】 The radar target signatures of the stealth aircraft are attractive to designers of radar and missile guidance. This paper presents some new target signatures, which include chi-square statistical model with small degree of freedom, wide-band frequency characteristics, harmonic response, polarization eigenvalues and bistatic scattering. It is shown that impedance loading on the surface of the stealth vehicles will enhance the glint and distort the image. Results from computer simulation are shown to agree to the theoretical estimates.更多还原
