基于探地雷达的土体空洞病害仿真模型研究
摘要
Abstract
In order to study the measurement conditions and accuracy of soil cavity disease size and location at different radar antenna frequencies,finite-time time-domain difference method is used to develop simulation model that calculates the variation of the radar antenna center frequency at different cavity sizes and depths.The results show that the energy of the low-frequency radar wave dissipates quickly,the wavelength is large,it cannot accept effective ground reflection wave,and the accuracy of small objects is not enough;when the cavity disease depth is less than 10cm,it needs to be higher than 900 MHz antenna can determine the type and size of the disease.When the disease size is 20 cm×20 cm,you need to choose an antenna more than 750 MHz frequency.When the disease size is 30 cm×30 cm,you need to choose an antenna more than 500 MHz frequency as a detection tool.关键词
