| 摘 要： | 超宽带脉冲体制探地雷达探测浅层目标一般以图象的形式给出结果，对探测人员读图能力要求较高，探测者的主观因素对分析结果影响较大；浅层目标体积小，埋设浅，回波比直达波的幅度小且容易与直达波混叠。基于这种雷达提出采用PCA算法计算能量分布变化曲线来检测浅层地下目标的存在，实现声音实时报警。这种方法在纯净和复杂环境下均具有较好的识别能力和报警效果。实验结果表明，PCA算法能够较准确的检测到浅层地下预埋目标的存在并实时报警，对今后浅层地下目标探测有一定指导意义。

| Abstract: | The research results of traditional Ultra-Wideband-Impulse-Ground-Penetrating Radar are used to be presented by images,which require the detectors to have excellent knowledge of echo pattern recognition.So the subjective factors of the detectors play a very important role in detecting.By calculating the energy distribution curve,an approach based on PCA algorithm to detect the existence of underground targets and sound alarm is presented in this paper.The method is tested on data containing mines on line,an... |
