摘　　要：研究了天线罩瞄准误差斜率对于雷达型导弹制导系统稳定性和脱靶量的影响,讨论了天线罩瞄准误差斜率的建模,根据已有建模方法的优缺点,提出用数据表格来描述俯仰、偏航平面上的天线罩瞄准误差,在此基础上进行查表法补偿,并通过数学仿真测试了该补偿方法,补偿精度满足要求。Radome error＇s negative effect on middle to high attitude stability and miss distance of radar homing missiles was introduced.The modeling of radome error slope was discussed.Considering the advantages and disadvantages of the existed modeling method,it was proposed to use data table to specify radome error of cross planes,and a lookup-table compensation method based on this model was used to solve the boresight error problem.Simulations were carried out and demonstrated that the stability and accuracy of missiles were improved significantly.
