本文采用脉冲多普勒雷达技术,测量了电离层高频返回散射回波的时延-功率-多普勒频率的三维频谱图.对典型的频谱图作了分析,并由谱图推算了电离层等效反射面的垂直运动速度,它与垂直探测资料推算的结果相符.
In this paper, the pulse-Doppler radar technique was used to measure the three-dimensional spectrum of the delay-power-Doppler frequency of ionospheric high-frequency backscattered echoes.The typical spectra were analyzed and the ionization The vertical movement velocity of the equivalent reflection surface of the layer is consistent with the result of the vertical detection data.
