The Wuhan Ionospheric Oblique Backscattering Sounding System with the addition of an antenna array (WIOBSS-AA) is the newest member of the WIOBSS family. It is a multi-channel radio system using phased-array antenna technology. The transmitting part of this radio system applies an array composed of five log-periodic antennas to form five beams that span an area to the northwest of the radar site. The hardware and the antenna array of the first multi-channel ionosonde in the WIOBSS family are introduced in detail in this paper. An ionospheric detection experiment was carried out in Chongyang, Hubei province, China on 16 March 2015 to examine the performance of WIOBSS-AA. The radio system demonstrated its ability to obtain ionospheric electron density information over a wide area. The observations indicate that during the experiment, the monitored large-area ionospheric F2-layer was calm and electron density increased with decreasing latitude.
武汉电离层斜向返回散射探测系统增加了一个天线阵列（WIOBSS-AA），是WIOBSS家族的最新成员。它是一个采用相控阵天线技术的多通道无线电系统。该无线电系统的发射部分应用由五个对数周期天线组成的阵列，形成五个波束，覆盖雷达站西北方向的一片区域。本文详细介绍了WIOBSS家族中首个多通道电离层探测仪的硬件和天线阵列。2015年3月16日在中国湖北省崇阳进行了一次电离层探测实验，以检验WIOBSS-AA的性能。该无线电系统展示了其在大面积区域获取电离层电子密度信息的能力。观测结果表明，在实验期间，监测到的大面积电离层F2层较为平静，电子密度随纬度降低而增加。
