本文详尽地论述了雷达寻的导引头的测量视线转动角速率误差,并且推导了各项误差的数学公式和工程计算方法。对于作用于雷达寻的导引头的起伏误差成份:导引头接收机内部杂声;目标杂声;目标机动以及弹体姿态耦合等随机成份做了定性和定量的讨论.对于主要的系统误差成份:导引头微分陀螺零位;电子伺服杂声零位;天线罩瞄准线误差率的影响;也做了分析计算。本文前两节对于导引头测量视线转动角速率误差作出了定 This paper discusses in detail the error of the measured angular rotation of radar seeker, and deduces the mathematical formula and engineering calculation method of each error. The fluctuation components of the seeker acting on the seeker are discussed qualitatively and quantitatively: stochastic components such as target noise, target maneuvering and projectile attitude coupling, etc. For the major systematic errors Components: seeker differential gyro zero; electronic servo noise zero; radome line of sight error rate of impact; also made analysis and calculation. The first two sections of this article set the angle of view for the seeker to measure the angular velocity error
