摘　　要：在复合制导体制下,导引头预定精度是影响中末制导交班的重要因素,在分析了制导交班主要误差源的基础上,提出用修正系数法对雷达测量误差造成的中末制导交班导引头预装误差进行分析。结合真实目标运动轨迹,利用此方法仿真计算了在地面制导雷达测量误差条件下中末制导交班的导引头预定方位角和俯仰角参数及其误差。仿真结果表明,修正系数法能够准确地分析多个不同参数对中末制导交班的影响,是研究导引头预定精度问题的一种有效方法。The presetting accuracy of seeker is an important factor for guidance handover in midcourse guidance combined with terminal guidance. Thus, based on the analysis of main guidance handover errors, a correction coefficient method is proposed in analysing the seekerg presetting accuracy due to the radar measurement errors. Integrated with the real target movement locus, the presetting parameters and errors of azimuth and elevation due to the command guidance radar measurement errors are computed. The simulation results indicate that the correction coefficient method can be used to exactly analyse the effects of different parameters on handover and it is an efficient way to research the seeker′s presetting accuracy problem.
