摘要: 随着高频通信、探测技术的发展,开展电离层侧向散射的研究具有重要意义.搭建了电离层侧向散射探测试验平台,基于该试验平台,进行了侧向散射探测试验,获得了群距离-频率-幅度的三维侧向散射电离图和地、海侧向散射来波谱图.试验结果表明,基于该试验平台,能够获取电离层侧向散射探测结果,为后续电离层侧向散射信道特性、地海杂波特性的深入研究奠定了基础.

Abstract: With the development of HF communication and sounding techniques,study on ionospheric sidescatter is of great importance.Ionospheric sidescatter experimental platform is built,and based on this experimental platform,ionospheric sidescatter sounding experiment is made.In the experiment,the (group)distance-frequency-amplitude three-dimensional sidescatter ionogram and sidescatter doppler spectra of sea and land are obtained.With this experimental platform,the ionospheric sidescatter sounding results can be obtained,which can establish a basis for further study on the characteristics of the ionospheric sidescatter channel and the land/sea clutter.

Key words: backscatter, sidescatter, ionospheric sounding, ionogram, Doppler spectrum
