三种不同的进气道与弹体组合体雷达散射截面特性

对三种不同进气道与弹体组合所得的三个模型进行了雷达散射截面（RCS）实验研究，三种组合分别为：埋入式进气道与多边形截面弹体的组合，埋入式进气道与常规圆截面弹体的组合、S弯进气道与常 圆截面弹体的组合，雷达散射截面特性实验和对比研究表明：圆截面弹身时，采用埋入式进气道比采用S弯进气道具有更好的隐身效果；采用埋入式进气道时，多边形截面导弹比圆截面弹身隐身性能更好。可以推断，多边形截面弹体与埋与式进气道的组合具有光明的应用前景。

Radar Cross Section Characteristics of Three Different Inlet-Body Missile Models

An experimental study of three different inlet body missile models is conducted in radar cross section(RCS) stealthy and the comparison of their RCS characteristics is presented. Among these three models,one is a round cross section missile model with a ground track field cross section S shaped inelt,one is a round cross section missile model with an elliptical section submerged inlet,and another one is a polygonal section missile model with a triangular section submerged inlet.The results show that the round cross section missile body with a submerged inlet is better in stealthy than the same missile body with an S shaped inlet;and the polygonal section missile body with the same submerged inlet is better in stealthy than the round cross section missile body.Thus it can be concluded that the polygonal section missile body with a submerged inlet has a bright future in application.
