摘　　要：随着对飞行器飞行精度和可靠性要求的提高,单一系统已无法满足系统要求,而采用先进的算法,利用信息融合技术将导航系统进行组合,取长补短,提高系统的综合性能成为主流,并得到迅猛发展。导航系统也呈现多信息化、智能化、集成化的发展趋势。本文根据捷联惯导系统(SINS)和塔康系统(TACAN)不同的导航特性,在卡尔曼滤波的基础上,将二者组合起来,编写SINS/TACAN组合导航的滤波算法,并对该组合导航系统进行仿真,仿真结果表明:卡尔曼滤波下的SINS/TACAN组合导航系统,有很高的可行性。Due to the increasing requirements of the accuracy and reliability of the aerocraft,a single system can＇t meet the system requirements.Hereby,the advanced algorithms are adopted,which promote the navigation systems integrated by using the information fusion technology.The new system learns from each other to improve the system performance,which becomes the mainstream and develops rapidly.The navigation system also presents multi-informationized,intelligentized and integrationized trends.According to the different navigational features of strap-down inertial system（SINS） and tactical air navigation system（TACAN）,the two systems are integrated by reforming the SINS/TACAN integrated navigation filtering algorithm and the simulation of the integrated navigation system is performed.The results show that the SINS/TACAN integrated system with the kalman filter has a very high feasibility.
