摘 要：随着物联网与人工智能在理论、方法和技术上的进一步融合和演进，人类对物理世界的感知已经进入泛在智能阶段。针对反向散射通信被动传感的感知机制和方法并不明确，通过混合感知的方式，可以观察到标签阵列中多标签感知信号的时空相关性，从而实现对感知结果的进一步理解。根据实验观察结果，得出了未来验证的假设。

Abstract: With the further integration and evolution of the theory, method and technology of the internet of things and artificial intelligence, human perception of the physical world has entered the stage of ubiquitous intelligence. The sensing mechanism and method of passive sensing for backscatter communication are not clear. Through mixed sensing, the temporal and spatial correlation of multi tag sensing signals in tag array can be observed, so as to realize the further understanding of the sensing results. According to the experimental observation results, the hypothesis for future verification is obtained.
Keywords: passive sensing equipment; RFID; sensing algorithm
