摘　　要：以导弹末制导系统分析为研究对象,针对仿真分析中应用的伴随技术、协方差分析法以及频域特性分析方法进行系统地阐述与比较,旨在得出各仿真技术的应用方法、所适用分析场合及各自的特点。首先对各仿真分析方法的原理分析,给出了应用伴随技术与协方差分析方法的仿真模型模型的建立方法。然后在时域表达的基础上推导出制导系统的频率响应与相关性能的解析表达式,并给出频域表达和时域分析的关系。通过对给定的制导系统模型进行仿真比较和分析得出了各仿真技术的特点和适用范围,同时仿真结果验证了频域分析方法的有效性及方便性。Based on general linearized missile endgame guidance system, three methods of homing loop analysis, adjoint simulation technology, covariance technology and frequency domain analysis were systematically presented. The model construction principles, basic theory and characteristics of each method were given. According to the prin- ciples of simulation model construction, analysis models of adjoint and covariance technology were established respec- tively. The analytical expressions for frequency response and related expressions for missile system performance were also given. The simulation results of specified guidance system show the efficiency and applicability of each simula- tion method.
