为了有效探测临近空间高超声速飞行器,分析了激波等离子体对电磁波的吸收、反射作用,讨论了激波等离子体单位距离衰减、反射系数和回波总衰减与雷达频率、电子碰撞频率的关系,并对其之间关系以及对不同波段电磁波的影响进行了仿真.仿真结果表明激波等离子体对微波段电磁波衰减较大.最后,对雷达
In order to effectively detect the near-space hypersonic vehicle, the absorption and reflection of the shock wave plasmon on the electromagnetic wave were analyzed. The relationship between the attenuation of the shock wave plasma unit, the attenuation coefficient of the shock wave and the total attenuation of the echo, the radar frequency and the electron collision frequency were discussed. And the relationship between them as well as the impact of electromagnetic waves in different wavebands are simulated.The simulation results show that the shockwave plasma attenuates the electromagnetic wave in the microwave band greatly.Finally,
