摘　　要：精密跟踪雷达中单脉冲测角是一种重要的技术体制,测角精度的好坏将关系到雷达对作战目标的跟踪性能。对于影响系统测角误差的诸多因素展开了较为全面的分析与研究,给出了各种噪声影响的测角误差数学模型。并在此基础上对测角精度有影响的接收机热噪声、目标振幅起伏噪声、目标角噪声、伺服系统噪声和多径传播噪声等因素进行了梳理、仿真,通过仿真结果给出了相互影响关系,文章的结论对于该类系统的设计与使用有一定的指导和帮助作用。The monopulse angle measurement is an important system technology for precision tracking radar. Radar angular accuracy will influence the performances of tracking. The factors that influence the measurement error of real system are analyzed and discussed, the angle error models of some noise influences are given. The receiver noise, target amplitude fluctuation noise, servo noise and multichannel noise are con strued. The simulation result shows the relationship between these factors, this will be helpful for developing advanced tracking radar systems.
