摘要
斜向探测是电离层探测的主要方式之一,它能够获得电波传播群时延和频率关系的电离图。由于传输信号的媒质是电离层,因此斜测电离图包含了收发站之间电离层状态信息,通过对斜测电离图的反演可以提取电离层的状态信息。利用遗传算法,对斜向探测电离层参数进行了反演,获得了较好的结果,展示了该方法在电离层参数反演研究中的优点和实际应用前景。结果证明该方法具有一定的抗噪能力,具有良好的应用价值。
The oblique sounding is one of the powerful tools, by which an oblique ionogram is obtained with the group path or time delay against operating frequency. Because of the communication media of ionosphere,the oblique ionogram contains useful state information which can be attained by inversion of the ionogram. Using the algorithm of Genetic,good results and its perspective for application are presented. The results prove that the method has performance of anti -jamming and has good value.
