Principal Component Analysis Method to Suppress TX/RX Coupled Interference

摘要

摘要: 在瞬態(tài)信號的測量系統(tǒng)中，收發(fā)天線的耦合信號是接收系統(tǒng)的主要干擾之一，對系統(tǒng)的性能有很大影響，尤其對近場遙感系統(tǒng)如表層穿透雷達(SPR)系統(tǒng)的影響更為明顯。故耦合波的去除對系統(tǒng)的信號處理性能起著至關重要的作用。該文依據(jù)SPR系統(tǒng)對信號處理的特定要求及其工作條件，提出了采用主元分析法去除直達波的方法。通過理論分析和具體試驗證明該方法可有效去除回波信號中耦合信號；此外，該處理算法簡單高效，易于實現(xiàn)實時處理。

Abstract: In a transient signal system, the TX/RX coupled interference is one of principle interferences and has great influence to the system capability, especially to the near field remote sensing system such as Surface Penetrating Radar(SPR). Suppression of the coupled interference is very important for the system performance. With consideration of the sys-tem operating condition, the signal and system character, realization object of the signal processing ,thc Principal Component Analysis (PCA) method is employed. The validity of the method for the engineering application is demonstrated with theoretical analysis and experiments in this paper, and it can bo applied to real-time processing.
