地雷场环境超宽带信号路径损耗特性研究

超宽带技术在地雷场中应用具有广阔前景和重大意义，已有的超宽带路径损耗模型不能满足地雷场环境的使用要求。为了实现超宽带技术在地雷场中的实际应用，通过建立地雷场环境模型，分析了超宽带信号传播的特点及规律。在理论分析基础上，推导出适用于地雷场环境的路径损耗模型并进行了数值模拟和实验测试。实验验证表明：建立的路径损耗模型比已有模型精度更高，能够准确反映地雷场环境中超宽带信号的传输特性，而且建立的模型形式非常灵活，能适用于不同的环境，为超宽带技术在地雷武器装备中的实际应用提供了依据。

Research on UWB Signal's Path Loss Characteristic in Minefield

The application of ultra wide band (UWB) technology in the minefield has good prospects and great significance. The existent path loss models of UWB can not satisfy the requirements in minefield environment. In order to make it practicable, a minefield model was established and the UWB signal's propagation features and laws were analyzed. Based on the theoretical analysis, a feasible UWB path loss model was put forward and the numerical simulations and experiments were also carried out. The results show that the new model can exactly reflect the UWB signal's propagation characteristic in the minefield and it is flexible and can be used in different conditions. The results can provide a basis for the application of the UWB technology in the mine weapons and equipment.
