【摘要】 等离子体的电子碰撞频率和磁感应强度是调节等离子体反射率的重要参量。本文应用矩阵算法,计算了电子密度为1016／m3、1017／m3时雷达波平均反射率随碰撞频率和磁感应强度的变化,确定了磁感应强度的调节范围和各波段中电子碰撞频率、磁感应强度的优化值,并在1017／m3的电子密度下得到了很好的宽波段低反射特征。更多还原

【Abstract】 The electronic collisional frequency and magnetic inductive intensity are important parameters of plasma for adjusting the reflectance. The matrix method is applied to compute the effects of electronic collisional frequency and magnetic inductive intensity on the average reflectance of radar wave when the electron density is 1016/m3 or 1017/m3. The range of magnetic inductive intensity, optimized collisional frequency and optimized magnetic inductive intensity have been determined. A broad low-reflectance band can be obtained when the electron density is 1017/m3.更多还原
