针对波束波导馈电天线无法对空间移动目标进行单脉冲跟踪的特点,首先分析了单脉冲跟踪角误差电压形成机理,同时定义了天线及馈源角误差坐标系,并通过分析常规天线及波束波导馈电天线跟踪移动目标时角误差电压特性,在国内首次得出了波束波导馈电天线跟踪空间移动目标的角误差电压坐标变换公式,最后,通过某波束波导馈电天线系统工程实践对该变换公式进行验证。结果表明,单脉冲跟踪角误差坐标变换模型完全满足波束波导天线对移动目标进行全空域高精度跟踪的要求。
In view of the fact that the beam-guided antenna can not track the target moving in monopulse mode, the formation mechanism of single-pulse tracking angle error voltage is firstly analyzed. At the same time, the antenna and the error angle of the feed-angle coordinate system are defined. By analyzing the conventional antenna and beam waveguide At the same time, the angular error voltage coordinate transformation formula of the space-moving target of the beam-guided antenna is obtained in the domestic for the first time. Finally, through the practice of a certain waveguide-fed antenna system engineering practice, Formula to verify. The results show that the monopulse tracking angle error coordinate transformation model fully satisfies the requirements of the beam waveguide antenna for tracking the moving target in the entire airspace with high precision.
