| 摘要: | 提出一种基于甚高频调频广播(VHF-FM)微波段的室内人体探测方法, 该方法是根据VHF-FM天线阵列接收机接收到的数据做空时相关处理得到信号子空间特征向量, 并将信号子空间特征向量映射为相应的代价值进行探测. 在静态无人, 室内环境没发生改变时, 代价值基本没有太大变化; 而当有人进入, 室内环境发生改变时, 代价值会发生明显的变化. 研究结果表明: 该方法能够很好地区分室内静态无人环境和动态有人环境, 且不容易受到噪声环境的影响, 具有稳定、准确的探测性能. |
| Abstract: | This paper presents an indoor human method based on VHF-FM microwaves. The method of detection is developed from the cost value which can be mapped by the corresponding eigenvectors. The eigenvectors are obtained using the space-time correlated processing data received by the antenna arrays. In a static state, the cost value remains almost constant, but it will change significantly when the indoor environment changes caused by people entering. The experimental results show that proposed method can well distinguish the indoor static-dynamic state change with good stability, accuracy and robustness. |
