摘要
与脉冲和脉冲编码电离层探测仪相比,介绍了一种宽带Chirp电离层探测仪,其具有硬件简单可靠,数据信号处理灵活,与其他无线电用户互扰性降低等诸多优点。结合软件无线电技术,在兼有脉冲电离层探测仪普通功能的同时,宽带Chirp电离层探测仪是在观测结束之后先将数据储存起来,然后进行信号处理,此过程提高了数据观测分析的灵活性,尤其进行特殊观测时非常有用,实现数据处理的多样性。最重要的是,宽带Chirp技术的使用,使Chirp电离层探测仪实现对电离层的垂直探测。
Compared to a pulse or impulse coding ionosonde,it is presented that a wideband Chirp ionosonde has many advantages,such as hardware with simplicity and reliability, digital signal processing flexibility, less mutual interference with other radio users and so on. Combined with software radio technology, a wideband Chirp ionosonde has common functions equivalent to those of the pulse,and data stored after observation and then processing enhances flexibility of data observation and analysis, especially some specific observation useful. It makes data processing variety. It is more important that application of wideband Chirp techniques makes Chirp ionosondes vertical sounding to ionosphere.
