摘　　要：为减少接收天线占地面积,降低架设难度,实现敏捷数字电离层测高仪的流动组网观测,设计了一种可用于1 MHz^30 MHz电离层回波探测的小型正交有源环天线,配合敏捷数字电离层测高仪,组成了具有多种工作模式的电离层高频回波探测系统.测试结果表明:该正交有源环天线与传统的正交折合偶极子天线相比,接收到的频高图质量基本相当,均可接收到电离层多次回波并区分电离层回波的O波与X波.结果表明:正交有源环天线在保证探测频高图质量条件下很好地解决了接收天线小型化问题,具有性价比高、架设简单的优点.为观测场地受限及需要临时流动观测的实际应用场景提供了良好的解决方案,具有广阔的应用前景.In order to reduce the size of the receiving antenna,make it easy to erect and realize the mobile observation of portable digital ionosonde,a small orthogonal active loop antenna for 1 MHz^30 MHz ionospheric echo detection is designed.The antenna,together with the portable digital ionosonde,constitutes an ionospheric high-frequency echo detection system with multiple operating modes.The results show that compared with the traditional orthogonal folded dipole antenna,the orthogonal active loop antenna has the same ability to receive the echo and multiple echoes of ionosphere,and can distinguish the O wave and X wave.The orthogonal active loop antenna addresses the problem of miniaturization of the receiving antenna under the condition of ensuring the quality of ionogram,and has the advantages of high cost performance and simple erection.It provides a good solution for the practical application scenarios where the observation site is limited and requires temporary flow observation.So this orthogonal active loop antenna has broad application prospects.
