【摘要】 近距雷达探测面临天线小型化和辐射方向图不对称等问题。本文以阵列天线为例,分别就收发共口径天线和收发双天线与目标位置之间的关系进行了系统性地研究。通过理论分析和仿真计算,直观地说明了两种天线的接收功率与目标天线之间垂直距离、天线单元个数、收发天线之间距离、目标天线之间径向相对距离的变化关系,得出在近距雷达探测时,收发共口径天线在接收信号方面具有明显优势,为感知-通信一体化,特别是近距雷达感知系统中的天线设计提供了参考价值。更多还原

【Abstract】 Short-range radar detection faces problems such as miniaturization of antennas and radiation pattern misalignment. In this paper,taken array antenna as an example,we study the relationship between the common-aperture antenna and the dual antenna as well as the target position systematically.Through theoretical analysis and simulation calculations,the relationship of these two kinds of antennas between the received power and vertical distance,the number of antenna elements,the distance between the transmitting and receiving antennas,and the radial relative distance,is intuitively explained.In short-range detection,the common-aperture antenna has obvious advantages in receiving signals.It provides reference value for the integration of sensing and communication,especially in the short-range radar sensing system.更多还原
