摘　　要：传统的无线电导航技术借助量子纠缠信号优越的特性可以突破所面临的技术壁垒,实现高精度的测量。结合量子照明的原理和腔电光力转换器,提出了一种基于量子微波纠缠信号的导航测距方案。通过将测距任务模型化为一个多目标假设测试问题,突破了量子照明中二元假设检验的限制。同时,通过理论分析和仿真,证明了所提测距方案在误差指数方面具有优势,且在测距精度上优于经典的测距方案。Objective Since the birth of navigation,it has had a huge impact on human life.At present,various navigation and positioning methods based on physical foundations such as sound,light,electricity,magnetism,and force have emerged one after another.Among them,the systems based on radio navigation technology for navigation and detection are the most common,radio navigation is still the main means used in the field of military and civil aviation navigation.Navigation is the process of guiding the safe navigation of the operating body.The main tasks include ranging,angle measurement and positioning,etc.These tasks are premised on obtaining the required navigation parameters.The navigation parameters are mainly divided into four types,namely position,angle,distance and speed.The position is a space-time parameter,including the time and space information of the running body.With the progress of the times and the growth of human needs,although the traditional navigation detection method is still the mainstream application in related fields,the detection accuracy is limited.Besides,it is easy to be interfered,the long-distance weak signal detection ability is not strong,and the safety performance cannot be effectively guaranteed.It has become increasingly prominent that traditional radio navigation methods will gradually fail to meet human needs for navigation.It is of great significance to study new navigation ranging solutions combined with quantum lighting to solve the above problems.Meanwhile,quantum illumination can only interrogate the presence of a target in one polarization-azimuth-elevation-range-Doppler-resolution area array at a time.It sends a signal to a narrow area and judges the presence of a target moving at a fixed speed at a fixed time,while practical navigation systems usually estimate the target's polarization properties,azimuth and elevation,distance and velocity(via Doppler effect).Therefore,it is of great significance to study new solutions to solve this problem and give full play to its advantages.M
