| 摘 要： | 针对有源相控阵天线的雷达散射截面(Radar Cross Section,RCS)计算复杂、缩减困难,以及RCS与辐射性能难以兼顾问题,基于阵面结构变形与安装引起的辐射单元位置偏移分析,利用辐射单元相位误差,建立了有源相控阵天线阵列散射因子RCS的机电耦合模型.并基于该耦合模型,应用粒子群优化算法,优化阵面所有辐射单元的安装高度,以实现有源相控阵天线辐射性能和散射性能的全优.仿真结果表明,所建立的耦合模型及综合优化方法能够在保证有源相控阵天线辐射性能的条件下,有效缩减其RCS,具有重要的工程应用价值.

| Abstract: | To efficiently compute and reduce radar cross section (RCS) of active phased array antenna, and to balance the performance of the radiation and scattering, a novel coupled structural-electromagnetic model of the array RCS factor of active phased array antenna is developed based on the phase errors of the array elements caused by antenna structural distortion and installation.According to the coupled model, the particle swarm optimization method is used to obtain the optimal installation height of all the array elements for the better radiation and scattering performances of active phased array antenna.The simulation results prove that the developed model and the integrated optimization method can effectively reduce the RCS of active phased array antenna with good radiation performances, which demonstrates an important application value in engineering. |
