| 摘 要： | 针对冲激体制的超宽带表层穿透雷达在时域接收中存在的射频干扰的问题,分析了射频干扰的性质与特征,并在此基础上,以MSE为准则,提出了A Scan的波形平均算法和B Scan方位向的中值滤波算法,并对实测的表层穿透雷达数据进行了处理。结果表明这两种算法都能较好地抑制SPR的RFI,最后对这两种算法的性能进行了比较和评估。

| Abstract: | With the appearance of radio frequency interference (RFI) in subsurface penetrating radar(SPR), this paper first analyzes the sources and properties of the RFI signal; and then based on the random property of RFI and the principle of mean square error (MSE),the wave-average filtering method in A-Scan and the median filtering method in B-Scan are discussed for RFI suppression. The performance of the two methods is demonstrated on data collected with SPR and the experimental results are also good. |
