米波雷达拥有反隐身、抵抗反辐射导弹的特长,其工作频率低,波长长,天线尺寸比较大。文中针对数字阵列米波八木天线的阵面稀疏庞大结构特点,探索机电联合仿真优化来解决米波雷达天线研制中的困难。通过天线参数优化、天线口径优化和天线精度优化等机电联合仿真优化,研究出新构型的八木天线,提高天线单元布置密度,降低雷达天线体积和质量,即能使雷达机动快速架设,又能确保天线的指向精度,满足雷达的性能指标。

The VHF radar has anti stealth and resistance of anti-radiation missile expertise, with low frequency, long wave, and relatively large antenna size. Aiming at the digital array VHF Yagi antenna of large sparse structure characteristics, we explore the electromechanical co-simulation optimization to solve the difficult of designing in VHF antenna. Through the electromechanical co-simulation including antenna parameter optimization, antenna aperture optimization and antenna accuracy optimization, a new configuration of Yagi is developed, the antenna layout density is increased. So it can reduce the volume and weight of the radar antenna. While it both can make the radar mobile rapid erection and can ensure the antenna pointing accuracy, full performance of radar.
