| 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阵元的双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，通过详细对比分析三种不同阵元排布方式下的天线性能，确定最优的布阵方式。仿真结果表明，该天线从0°~102.5°扫描过程中，天线增益大于13.3 dBi，增益波动小于2.5 dB。该相控阵天线能够适用于全空域多目标通信的场合。 |

| Abstract: |
| To satisfy the future demand for multi-target communication in hemispherical coverage,a 32-element dual circularly polarized spherical conformal phased array antenna is present.Hemispherical and cylinder configuration is adopted to meet the communication requirements at low elevation angel.Three spherical phased array antennas(SPAA) operating in different element distributions are compared in detail to decide the optimum performance.Simulation results show that the gain is higher than 13.3 dBi and the gain flatness is less than 2.5 dB within the scanning range of 0°~102.5°,which indicates this spherical phased array antenna can be applied in multi-target tracking in hemispherical coverage. |
| Key words: hemispherical coverage multi-target tracking spherical phased array conformal array antenna |
