一種多通道探地雷達(dá)數(shù)據(jù)實(shí)時(shí)融合方法
[Abstract]:According to the requirements of different engineering examples, a new processing method is proposed to enable the multi-channel ground penetrating radar to output all channel information in one view in real time. Based on the data fusion technology, the method is divided into three steps: first, pre-processing, such as bandpass filtering, space-time calibration and coordinate transformation; Then, the information entropy is used as the measure parameter and the weighted average fusion criterion is used for real-time calculation. Finally, the automatic gain is used to compensate and enhance the fusion data. The real-time fusion result of multi-channel ground penetrating radar data can display all the detected targets or anomalies simultaneously. According to the information entropy of each channel, it can locate the target quickly at the same time. This method makes the data display of multi-channel ground penetrating radar break through the limitation of traditional method, improve the lag, and meet the requirement of rapid target location in engineering application.
