【摘要】:針對不同工程實例的需求,采用新的處理方法,使多通道探地雷達能在一個視圖中實時輸出所有通道信息。該方法以數(shù)據(jù)融合技術(shù)為基礎(chǔ),具體實現(xiàn)分為三步:首先,進行帶通濾波、時空校準和坐標轉(zhuǎn)換等預(yù)處理;然后,采取信息熵這一度量參數(shù)和加權(quán)平均的融合準則進行實時計算;最后,利用自動增益對融合數(shù)據(jù)補償、增強。多通道探地雷達數(shù)據(jù)實時融合結(jié)果能同時顯示所有通道檢測到的目標或異常,根據(jù)各通道信息熵的大小,能在發(fā)現(xiàn)目標的同時進行快速定位。該方法使多通道探地雷達的數(shù)據(jù)顯示突破了傳統(tǒng)方式的局限性,改善了滯后性,滿足了工程應(yīng)用對目標快速定位的要求。
[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.
