摘要
金属目标表面涂覆吸波材料可以有效地抑制雷达散射截面（ＲＣＳ）。本文推导出光滑凸体金属表面涂覆吸波材料时的后向雷达散射截面公式。对一系列涂覆平板的ＲＣＳ进行了测试和理论计算。研究发现：对于平板而言，ＲＣＳ减缩量的理论计算与实验的差值随着涂覆面积的增大而增大。为此，给出一种工程修正的方法，从而提高计算精度。
Radar Cross Section(RCS) is efficiently controlled by coating material (RAM) for metal objects. A formulation of RCS for smooth convex metal objects with coating RAM is derived in this paper. RCS has been measured and calculated for a lot of metal planes with coating RAM.The result of study shows that the difference of reduced RCS between theoretical calculation and measurement increases with the increase of coating area. To improve accuracy of calculation. an engineering correction is given.
