摘要
针对探地雷达成像需要自动放大感兴趣目标区域,同时抑制其他背景区域问题,提出了一种感兴趣目标区域自动插值方法.该方法通过二次统计检测地下目标的水平位置,且自动分割测线,之后用菱形模板预处理目标测线,用统计方法自动检测出目标深度位置,并对目标区域进行相关增强,最后对感兴趣的目标区域用实时插值方法放大,同时抑制背景.在不同的应用场合可选取相应模型,不仅实现感兴趣目标的自动检测,而且对目标区域实现自动增强,有利于目标定位和识别.实测数据表明该方法具有很好的适应性和可靠性.
It is necessary to amplify the area of the targets of interest in ground penetrating radar （GPR） while restraining background for artificial recognition. The paper presentes an algorithm for automatically interpolating in the area of targets of interest, which is based on twice statistics to automatically detect the transverse position of the targets of interest in GPR with the echoes of the target separated. The detected echoes of the target are preprocessed by the damond template. In ram, the method of statistics is used to determine the depth of the target. The area of targets of interest is enhanced by the correlation. Finally, the target is amplified by bilinear interpolation while the background is restrained. The different model is selected in a different application so that it not only realizes detection of targets of interest but also automatically enhances targets. Moreover, the algorithm is benefitial to locating and recognizing the buried targets. Te results of test by raw data show that the method is well adaptive and reliable.
