摘要
为了验证2.6GHz频段中,室内的实际穿透损耗情况,提出基于卡尔曼滤波的2.6GHz频段信号室内穿透损耗检测方法。测算穿透性高分辨率检测波形,采用卡尔曼滤波下设计弹性波动信号导出结构,进行迭代双节点检测模型的创建。最后,采用频域法实现2.6GHz频段信号室内穿透损耗的检测。最终的测试结果表明:在不同的辐射深度环境下,对比于传统的接地信号检测组以及传统声波穿透检测组,本文所设计的卡尔曼滤波检测组最终得出的检测偏差相对较低,更好地表明此检测方法在面对复杂检测情况时,可以形成更佳的频段控制环境,对于室内的损耗与穿透情况进行强化控制,具有更强的实际应用意义。
In order to verify the actual indoor penetration loss in the 2.6 GHz frequency band, a Kalman filter-based indoor penetration loss detection method for signals in the 2.6 GHz frequency band is proposed. Measure the penetrating high-resolution detection waveform, use Kalman filter to design the elastic fluctuation signal derivation structure, and create the iterative two-node detection model. Finally, the frequency domain method is used to achieve indoor penetration loss detection of 2.6 GHz band signals. The final test results show that: in different radiation depth environments, compared with the traditional ground signal detection group and the traditional sound wave penetration detection group, the Kalman filter detection group designed in this paper finally obtains a relatively low detection deviation, and more It is a good indication that this detection method can form a better frequency band control environment when facing complex detection situations, and strengthen the control of indoor loss and penetration, which has stronger practical application significance.
