Design of an Ultrawideband Ionosonde

In this letter, an ultrawideband ionospheric sounding system was designed for ionospheric research and communication channel management. The frequency band of this ionosonde ranges from high frequency to very high frequency. It can be flexibly used at both monostatic and bistatic stations as a GPS receiver module was integrated. The system design includes three major components: control system, transmitting system, and receiver system. The operational parameters, such as frequency, waveform, and modulation type, can be manually reset. Correlation and Fourier algorithms are used to obtain a high signal-to-noise ratio and enlarge the detection range. The typical experimental results demonstrate that the proposed system can be used to study the ionosphere effectively.

在这封信中，设计了一种用于电离层研究和通信信道管理的超宽带电离层探测系统。该电离层探测仪的频段从高频到甚高频。由于集成了一个全球定位系统（GPS）接收模块，它可以灵活地用于单站和双站。系统设计包括三个主要部分：控制系统、发射系统和接收系统。频率、波形和调制类型等操作参数可以手动重置。采用相关算法和傅里叶算法来获得高信噪比并扩大探测范围。典型的实验结果表明，所提出的系统可有效地用于研究电离层。
