摘要
对亚密湍流等离子体尾迹的雷达散射特性进行了分析、研究和计算。讨论了圆柱形等离子体尾迹径向厚度、雷达波入射频率和入射角等因素对雷达散射截面的影响。尾迹中散射场的计算采用矩阵法求解,用一阶畸变波Born近似完成亚密湍流等离子体尾迹雷达散射截面积(RCS)的计算。分析和计算结果表明,雷达波入射频率和入射角、尾迹的径向厚度对RCS值影响较大,并且计算所得的尾迹雷达散射截面方向图可为再入体的雷达识别和隐身提供帮助。
This paper analyzes, studies and calculates the radar scattering characteristics of low density turbulent flow plasma wake, discusses the influence of the radial thickness of the cylindrical plasma wake,the incident frequency and incident angle of radar wave on the radar cross section (RCS). The scatter field in the wake is calculated by the matrix method, the RCS of the low density turbulent flow plasma wake is calculated approximately by the first order distorted wave Born. Analysis and calculation results show that the incident frequency and incident angle of radar wave, radial thickness of wake have significant influence on the value of RCS,and the calculated RCS direction patterns can supply the assistance for radar identification and stealth of the reentry vehicle.
