摘要

In view of the problems encountered in the work of coal mine safety production,a new type of real-time dynamic monitoring radar was proposed,another name is the intelligent prediction and prediction technology of radar beam scanning.At the same time,compared with the traditional frequency domain method,the time domain method has the advantages of reliable accuracy,faster calculation speed,and can truly reflect the essence of electromagnetic phenomena.Therefore,in the time domain demonstrates the array antenna in near field radar can form the main beam by effective radiation,the feasibility of realizing the radar beam scanning by means of cell delay control was demonstrated,the optimized design and simulation design of broadband loaded antenna were presented.The prototype was tested.The results show that the real-time dynamic monitoring radar has the function of radar beam scanning,and the technology can enhance the anti-jamming ability of the system,it can carry on the real-time dynamic monitoring,the intelligent forecast and the improvement of the underground detection result,and has certain social and economic benefits,and has wide application value.%针对煤矿安全生产中遇到的问题,提出了一种新型的矿井实时动态监测雷达,即雷达波聚束扫描探测的智能预测预报技术.鉴于时域方法与传统的频域方法相比较,具有可靠的精度,更快的计算速度,并能够真实地反映电磁现象的本质,在时域中论证了阵列天线在雷达近场区是可以形成有效辐射主波束的,论证了通过单元延时控制来实现雷达波聚束扫描的可行性,进行了宽带加载天线的优化设计和仿真设计,并基于样机进行了试验.结果表明:矿井实时动态监测雷达具备了雷达波聚束扫描功能,且该技术增强了系统的抗干扰能力,可进行实时动态监测、智能预测预报、改善地下探测结果,具有一定的社会和经济效益,有广泛的推广应用价值.
