针对粮仓的特殊应用环境，从雷达探测品质因子出发，根据粮仓仓底散射截面特性，结合粮食介质的衰减因子，推导出雷达最大探测深度计算公式，并对影响探测深度的因素进行了仿真分析畅依据本文的计算方法选取合适的雷达系统和发射频率进行了探仓实验，准确地探测了储粮深度。

英文摘要：

According to the special application environment of granary ,from the radar detection quality factor and the scattering cross-sectional characteristic of granary ’ s bottom and combined with attenuation factors of grain medium , the calculation formula of radar ’ s maximum investigation depth was deduced and a simulated analysis on factors which influence the investigation depth was made .Finally,the appropriate radar system and radiation frequency in accordance with the calculation method in this paper were selected to conduct the experiment of granary detection and detect the granary ’ s depth accurately .
