利用最优平滑技术对弹栽捷联惯导传递对准精度进行评估，是分析导弹系统的战术性能的有效方法。主要探讨了以载机主惯导为参考系统的弹载捷联惯导试验评估专家系统的设计方案，论述了评估系统设计时要考虑的问题。并采用固定区间平滑算法对系统设计的正确性进行了初步的仿真验证。通过对仿真结果的分析，证实了评估系统的可行性和有效性。

The optimal smoothing technology was used to test and evaluate the accuracy of air transfer alignment, which was an effective method for analyzing the tactical performance of the missile. The design scheme of an expert system for testing and evaluating of the SINS onboard the air-to-air missile is discussed, taking the airborne master inertial navigation system as the reference system. And some primary problems that should be taken into consideration in design are indicated. Fixed-interval smoothing algorithm was used for initial simulation and validation of the system design. Analysis to simulation result proved the feasibility and effectiveness of the designed evaluation system.
