摘要
针对全空域多目标通信的应用需求,设计了一种具有32单元的圆极化半球面相控阵天线。为满足低仰角目标通信需求,采用半球加圆柱的布阵方式,通过详细对比分析不同激活角域与单元增益下的阵列性能,确定最优的阵列设计。仿真结果表明,该天线从0°~90°扫描过程中,天线增益大于13.8 dBi,增益波动小于1.8 dB,能够适用于全空域多目标通信的场合。
To satisfy the future demand for multi-target tracking in hemispherical coverage,a 32-element circular polarized semispherical conformal phased array antenna is present in this paper.Hemispherical and cylinder configuration is adopted to meet the communication requirements at low elevation angel.Activate corner domain and different element distributions are compared in detail to decide the optimum performance.Simulated results show that the gain is higher than 13.8 dBi and the gain flatness is less than 1.8 dB within the scanning range of 0°~90°,which indicates this spherical phased array antenna can be applied in the occasions of multi-target tracking in hemispherical coverage.
