摘　　要：基于＂速度＂＋＂姿态＂的匹配方法,分析了影响传递对准精度的主要因素,针对机载武器系统惯性器件选择验证反复、挂飞代价大、验证周期长等问题,结合其工作特点,提出一种实用的传递对准仿真和验证思路：结合载机可能的机动情况,采用三种仿真方案进行计算机仿真,初步确定系统惯性器件精度等级;利用现有精度等级相当的同类产品进行实验室半实物仿真验证实验,通过实验验证,表明采用的传递对准方法和惯性器件选择的合理性,为实物研制提供重要依据,并为挂飞实验奠定基础。On the basis of matching method of ＂velocity＂＋ ＂attitude＂,it make an analysis on the main factors that affect the transfer alignment accuracy in this paper.And,for these problems,such as,repeat verfication of inertial component choice,high cost in flying test and long test period,which exist in the airborn weapon system,it put forwards a practical idea of tranfer alignment and verification with conbimation of the work property of weapon.Also,three simulation solutions are adopted to make computer simulation with the combination of carrier possible maneuver.First,the precision grade of sensing elements of the weapon system is decided.Then,according to the required precision,the semi-physical simulation experiment is carried out with the existing equivalent product with the corresponding precision grade in the lab.The experiment result is shown that the used transfer alignment method and inertial component choice is reasonable.This offers the significant foundation for development and flying test.
