天气雷达低噪声放大器的仿真设计

The intersection of Quantum Technologies and Robotics Autonomy is explored in the present paper. The two areas are brought together in establishing an interdisciplinary interface that contributes to advancing the field of system autonomy, and pushes the engineering boundaries beyond the existing techniques. The present research adopts the experimental aspects of quantum entanglement and quantum cryptography, and integrates these established quantum capabilities into distributed robotic platforms, to explore the possibility of achieving increased autonomy for the control of multi-agent robotic systems engaged in cooperative tasks. Experimental quantum capabilities are realized by producing single photons (using spontaneous parametric down-conversion process), polarization of photons, detecting vertical and horizontal polarizations, and single photon detecting/counting. Specifically, such quantum aspects are implemented on network of classical agents, i.e., classical aerial and ground robots/unmanned systems. With respect to classical systems for robotic applications, leveraging quantum technology is expected to lead to guaranteed security, very fast control and communication, and unparalleled quantum capabilities such as entanglement and quantum superposition that will enable novel applications.     

南海海岛自动气象站数据双通道传输系统设计与实现

为解决海南省南沙区无人海岛自动气象站单一GPRS数据上传通道数据到报率不高的问题，文章利用北斗卫星通信的优势，首先在硬件上增加基于北斗卫星的通信终端机和配套的供电系统实现海岛站GPRS和北斗通信双通道并行运行；其次将每个通道定义为1个逻辑站点，2个逻辑站点组成1个观测系统，上传1份数据报文，通过本地终端实现观测数据的本地化应用。文章同时分析了改造前后数据到报率等情况，所得结论可以进一步提升岛礁防灾减灾水平。
