摘　　要：塔康系统作为我军主用的战术空中导航系统,是能够实现点源定位,而且性能可靠的传统陆基无线电导航系统,在战术编队、航路导航及归航引导等方面发挥重要作用。在当前卫星导航系统应用存在抗干扰性差,抗毁能力弱的现实条件下,发展能够降级使用的备份无线电导航手段具有迫切性和现实性。而开发利用塔康系统作为备份的前提是使其具有较高的导航定位精度。设计了一种新型测距信号,利用其自相关特性提取关键的定时信息,实现塔康定位精度的提升。在信号格式、测距精度、对系统性能的影响等方面进行仿真分析,结果表明新的信号形式能够在理论上有效提升塔康测距精度。在新体制信号的基础上分析测距效果,进而提高塔康导航系统的战技性能,并为新一代测距技术提供借鉴。Being the main radio short-range navigation system in our army,and enabling to realize the point source positioning with reliable performance,TACAN system,the only traditional land-based radio navigation system,plays an important role in route navigation and homing guidance.Under the current realistic conditions that anti-interference is poor and anti destruction ability is weak in the application of satellite navigation system,it is urgent and realistic to develop and make good use of TACAN system to improve its navigation and positioning accuracy and make it a radio navigation means with high positioning accuracy and wide coverage.Taking developing and utilizing the TACAN system as a premise to backup means that there is a quite good precision in navigating and positioning.By analyzing the ranging technology implementation ways and performance indexes of other navigation and positioning systems,the code related ranging methods and implementation technologies of TACAN system are studied,and the simulation analysis is carried out in the aspects of signal format,ranging accuracy and impact on system performance.The effect of ranging by using new coded signal is helpful to improve the tactical and technical performance of TACAN navigation system,and can also be used for the development demonstration of TACAN system equipment,and provide reference for the new generation of ranging technology.
