高功率微波大气传输轨迹模拟

Simulation of High Power Microwave Propagation Trace in Atmosphere

高功率微波在大气中传输时,会发生大气折射效应,折射效应的显著程度主要依赖于沿路径的折射指数变化梯度和射线初始仰角。本文根据低层大气剖面数据,将高功率微波在大气未击穿时的传输轨迹划分为若干个点,分析计算出各点对目标的仰角、高度、地心夹角和到发射站的真实距离,实现了对高功率微波大气传输轨迹模拟。

When high power microwave is propagating in atmosphere, the effect of atmospheric refraction will take place and the extent of it mainly depends on the variation gradient of refractive index and the initial quadrant elevation according to path. Based on the lower atmosphere section data, this paper divides the propagation trace of high power microwave when the atmosphere is not breakdown by some points, get the quadrant elevation, altitude, geocentric separation angle from every points to the target point and the true distance from every points to the emission point and realize simulation of high power microwave propagation trace in atmosphere.
