摘　　要：针对空空导弹的传递对准精度评估问题,提出了采用GPS伪距/伪距率作为观测量的传递对准精度评估方法。在建立传递对准精度评估模型后,采用RTS固定区间最优平滑算法对传递对准精度进行评估。针对所提出的评估方法设计了评估软件进行仿真验证,结果表明所提出的评估方法能够对传递对准的精度进行有效的估计。Focusing on the problem of airborne missile transfer alignment accuracy evaluation, a method which takes GPS pseudo-range/pseudo-range rate as measurements is proposed. After establishing the transfer alignment evaluation model, RTS fixed interval optimal smoothing algorithm is used to estimate the transfer alignment accuracy. An evaluation software is designed to verify the proposed method. The simulation results indicate that the proposed evaluation method is effective to estimate the transfer alignment accuracy.
