摘　　要：随着超高速飞行器的出现,航空测控中传统的一维机械天线跟踪目标已经越来越困难,而相控阵天线却十分适合使用。均匀直线阵作为相控阵天线基本的阵列形式应用广泛,适合航空测控系统采用。为此构建了均匀直线阵模型,并对均匀直线阵采用比相单脉冲跟踪测角的原理进行了研究,获得了归一化角误差的数学表达式,建立了波束跟踪反馈系统,并就均匀直线阵对空间目标跟踪测角进行了探讨。最终结合航空测控系统的典型应用模式,对前述结论进行了仿真验证。In aeronautical TT＆C system, the traditional ID mechanical tracking antenna can be hardly competent for tracking ultra high-speed aircraft, which becomes more and more severe, and the phased-array system can meet the demand perfectly. The uniform linear array antenna is a basic form of phased-array system and easy to be adopted. For this reason, a model of uniform linear array antenna system is constructed, and the mechanism of phase comparison monopulse auto-tracking system and the function of uniformed angle error are deduced based on this model. Then a beam auto-tracking feedback system is built, and the application of uniform linear array in spatial target angular measurement is discussed. Simulations are processed to validate the performance of beam auto-tracking feedback system, based on a uniform linear array antenna.
