发布时间:2018-10-31 19:08
【摘要】:针对不同工程实例的需求,采用新的处理方法,使多通道探地雷达能在一个视图中实时输出所有通道信息。该方法以数据融合技术为基础,具体实现分为三步:首先,进行带通滤波、时空校准和坐标转换等预处理;然后,采取信息熵这一度量参数和加权平均的融合准则进行实时计算;最后,利用自动增益对融合数据补偿、增强。多通道探地雷达数据实时融合结果能同时显示所有通道检测到的目标或异常,根据各通道信息熵的大小,能在发现目标的同时进行快速定位。该方法使多通道探地雷达的数据显示突破了传统方式的局限性,改善了滞后性,满足了工程应用对目标快速定位的要求。
[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.
