摘要
执行地面目标检测任务的机载相控阵雷达通常采用前视阵.介绍了机载相控阵雷达中的前视圆面阵的结构,推导了天线的方向图的计算模型,并就口径场分布为均匀分布的情况下的方向图进行了仿真分析.所得结果有助于研究基于前视圆面阵的空时自适应处理.
Forward looking array is commonly used in GMTD. This paper introduces the structure of forward looking circular planar array antennas for phased array radar. The patterns of the forward looking circular planar array antennas are derived. Some results of simulation and analysis of the patterns are given when the apperture distribution is uniform. The results obtained are helpful to research STAP based on forward looking circular planar array antennas.
