摘要
为准确探测出粮仓中的异物或空洞的大小和位置,进而精确测算出粮仓储粮数量,将探地雷达技术应用到粮仓异物探测上,并结合粮食介质和粮仓结构的特点,建立了粮食介质中的雷达方程和粮仓探测的雷达回波信号模型.外场实验结果表明,对探地雷达频率和回波信号处理方法进行适度改造后,利用探地雷达技术对粮仓进行异物探测完全能够满足实际的需要.
To accurately detect the size and location of foreign-body and cavity distinguished from grain, and then precisely calculate the quantity of the grain, the ground penetrating radar technique was applied to the granary detection, and based on the characteristics of grain mediium and granary structure, radar equation corresponding to grain medium and radar echo signal model for granary detection were established. The outfield experiment showed that it could completely meet the need of detection of the foreign-body in granary using ground penetrating radar technique as the frequency of ground penetrating radar and echo signal processing method were properly improved.
