Wigner Frequency Point Slice Analysis of Superposition Data for Phased-Array Ground Penetrating Radar

摘要

According to the frequency property of Phased-array ground penetrating radar (PGPR), this paper gives a frequency point slice method based on Wigner time-frequency analysis. This method solves the problem of analysis for the PGPR’s superposition data and makes detecting outcome simpler and detecting target more recognizable. At last, the analytical results of road test data of the Three Gorges prove the analytical method efficient.
