摘　　要：主要研究了大气层外等离子体隐身机理之一——等离子体对电磁波的碰撞吸收,建立了等离子体碰撞频率及其对电磁波碰撞吸收的计算模型,完成了不同电子密度和中性粒子密度下碰撞频率的计算与分析,等离子体对电磁波能量碰撞吸收效果的计算与分析,获取了等离子体对电磁波能量碰撞吸收效果随等离子体参数变化规律,给出了几点研究结论。The plasma collisional absorption of electromagnetic wave upper the aerosphere is studied in this paper. Two computation models are founded, one is the collision frequency of plasma, the other is the plasma collisional absorption of electromagnetic wave. The collision frequency of plasma in different densities and plasma collisional absorption energy of electromagnetic wave are computed and analyzed. By computing and analyzing, the variety disciplinarian of plasma collisional absorption of electromagnetic wave under different parameters is obtained, and some conclusions of low frequency and wide frequency band collision absorption stealth are offered.
