一种新型复合探雷系统的设计和实现

Design and Realization of a Novel Landmine Detect System with Dual Sensors

为了解决传统探雷器易受复杂土壤环境和各种干扰物的影响造成误报率过高的问题,提出了一种基于电磁感应(EMI)和探地雷达技术(GPR)的复合探测系统及其设计方案,通过将两种完全不同探测机理的传感器数据进行融合处理,协同工作,提取地雷目标特征信号,结果表明:可有效提高地雷的探知率并降低误报率,克服采用单一探测技术探雷器难以解决的原理性虚警问题;通过样机试验结果验证了设计方案的有效性。

In order to decrease the high false alarms effected by varies of edatopes and interferents when using traditional mental detector,which has only one type of sensor,to detect landmine,a new detect system with dual sensors based on electromagnetic induction(EMI)and ground-penetrating radar(GPR)technology was proposed.By combing data acquired from two types of sensors and extracting landmine features,this system could improve accuracy and reduce false alarms significantly,as well as overcome typical errors using ordinary mental detector.The design is verified effective by some tests.
