【摘要】 本文以组合导航系统为研究对象，重点研究了捷联惯导系统与被动雷达系统的组合导航系统，为捷联惯导系统与被动雷达系统组合实现远距离、自主导航提供了重要的理论依据和实践方法。论文简要介绍了雷达随动系统的工作原理，列举了雷达随动系统的几种常见设计方案，通过性能比较，选择了一种电动平台伺服式的随动系统设计方案，给出了系统的参数设计。最后，对满足设计要求的系统的工作过程及性能分析做了详细说明。本论文在对捷联惯导系统的基本原理、算法及力学编排做了详细介绍的基础上，对捷联惯导系统进行了仿真研究。为了对假定弹道轨迹进行分析研究，设计了飞行状态数据发生器，产生仿真用的输入信号，并取得不错的效果。论文对高度通道作了详细的研究，重点对组合高度通道的二、三阶阻尼形式的回路的性能了进行了分析。本论文给出了捷联惯导系统与被动雷达导引头随动系统的信息交换方案，利用捷联惯导系统自身提供的信息以及一些外部先知信息，实时计算导弹的视线角，并让被动雷达导引头的随动系统跟踪视线，可以保证在捷联惯导允许误差的范围内雷达导引头时刻对准目标。这样在被动雷达开机后，能快速搜索到目标。论文最后在介绍了被动雷达信号特征及卡尔曼滤波算法的基础上，给出在末制导段捷联惯导系统与被动雷达系统异类传感器的信息融合方案。更多还原

【Abstract】 Taking integrated navigation system as the object, the integrated navigation system of the SINS and the passive radar is studied mainly. In this paper, an important proof is provided by theory and practice for the integrated navigation system to guide for a long distance independently.The operating principle of the following-up system of the passive radar is simply introduced, and some several commonly -used design schemes are given. Then a electromechanical platform servo following-up system scheme is chosen by comparing, and the parameters of the system are determined by the way of frequency behavior. Finally the process and performance of the system are particularly described.On the base of introduction of the basic principle of SINS, algorithm and mechanics arrangement, the SINS is programmed and studied. To analyse the supposed trajectory, the flight state data generator is designed to generate the simulating input signals and good effect is gained in simulation. In the paper, the vertical channel of the SINS is also specially studied, which emphasis is put on the performance analysis of the second order and the third order damping loop.In the paper, the scheme of information exchange between the SINS and the passive radar is proposed. In the case of the calculation of the angle of the line of sight with SINS information itself and some exterior precognitive information, and the seeker track of the angle, the target can be aimed at by the seeker of passive radar, if the error of SINS is ignored. Then after the passive radar boost-strap, target can be quickly searched. With the foundation of the introduction of the character of the passive radar signal and the algorithm of Kalman Filter, the information fusion scheme of the heterogeneous sensors, the SINS and the passive radar, is presented at the terminal guidance section.更多还原
