电磁矢量传感器多输入多输出(electromagnetic vector sensor multiple-input multiple-output,EMVS-MIMO)雷达是一种新兴技术,可实现二维波达角(2D-DOA)估计。针对单基地稀疏阵列EMVS-MIMO雷达,提出一种基于旋转不变性信号参数估计技术ESPRIT(estimation of signal parameters via rotational invariance techniques)的降复杂度(reduced-complexity,RC)信号参数估计算法,能够实现对目标2D-DOA的快速估计。首先,对接收阵列数据进行RC处理,以消除阵列冗余数据;其次,利用ESPRIT可获得高分辨率的俯仰角估计,由于阵列的稀疏性,该估计值具有模糊性;再次,利用矢量叉积技术获得具有无模糊特性的2D-DOA;最后,利用无模糊的俯仰角估计对有周期模糊的估计进行解模糊,获得具有高分辨率、无模糊特性的俯仰角估计。该算法适用于大规模EMVS-MIMO雷达系统,且相比现有的ESPRIT-Like算法拥有更高的估计精度,通过MATLAB仿真验证了算法的有效性。
“指挥信息系统工程”课程是指挥信息系统工程专业的核心课程。针对“指挥信息系统工程”课程中存在缺少思政教学设计、相关知识体系和教学资源待更新完善、教学效果不够好等问题,分析了“指挥信息系统工程”课程思政的实施路径,从“指挥信息系统工程”课程教学体系改革研究、课程思政的解决途径、基于“互联网+”的教学目标评价方法研究、课程思政教学资源四个方面探索了“指挥信息系统工程”课程思政建设路径,为提高“指挥信息系统工程”课程的建设质量和教学效果提供可行解决途径。The course of “Command Information System Engineering” is the core course for the major of command information systems engineering. In view of the problems in the course of “Command Information System Engineering”, such as the lack of ideological and political teaching design, the need to update and perfect the relevant knowledge system and teaching resources, and the insufficient teaching effect, this paper analyzes the implementation path of the course of “Command Information System Engineering”, and probes into the ideological and political construction path of the course of “Command Information System Engineering” from four aspects: the reform of the teaching system of “Command Information System Engineering”, the ways to solve the ideological and political problems of the course, the evaluation method of teaching objectives based on “Internet+”, and the teaching resources of the course ideological and political problems. It provides a feasible solution for improving the construction quality and teaching effect of the course of “Command Information System Engineering”.
