| 摘 要： | 在电离层返回散射探测中,回波信号容易受到射频干扰(RFI)的污染,使得直接从回波信号中提取电离层信息比较困难,因此对这些干扰进行剔除是必不可少的。基于波形平均算法和小波变换去噪算法,提出一种剔除射频干扰(RFI)和噪声的方法,并对实测数据进行了处理。结果表明:将该算法应用到电离层返回散射探测中是可行的。

| Abstract: | In ionosphere backscattering detection,the echo signal is easily contaminated by radio fre- quency interference（RFI）,which makes it difficult to extract the ionosphere information from echo signals,so eliminating the interference is absolutely necessarily. Based on waveform even algorithm and wavelet transform denoise algorithm,this paper presents a method to eliminate RFI and noise, and performs processing to the data measured practically. The result shows：it is feasible to apply the algorithm to the detection of ionosphere backscattering. |
