中文摘要：
为达到无线射频注入的定位精度和实时性要求,提出采用递推最小二乘算法（RLS）进行定位。首先讨论了无线射频注入的定位精度需求,建立了机载无源单站定位模型,得出了最小二乘（LS）解。然后依据无线射频注入的实时性要求将其转化为递推形式。仿真结果表明,RLS算法与LS算法的定位精度和收敛速度接近,但前者实时性好,运算复杂度低,所需存储空间小,能够满足无线射频注入的定位需求。最后依据仿真结果给出了提高定位精度和收敛速度的措施。
英文摘要：
To achieve location accuracy and real-time requirement for wireless radio frequency injection,a recursion least-squares（RLS） estimation algorithm is proposed.Firstly,this paper discusses location accuracy requirement of wireless RF injection,builds single airborne observer passive location model,and obtains least-squares（LS） solution.And then a recursion form is deduced according to real-time requirement of wireless RF injection.Simulation result shows that location accuracy and convergence rate is closed,but the former has good real time,low operation complexity,small memory space needs,which can achieve the requirement of wireless RF injection.At last,the measurements to improve location accuracy are presented by the simulation results.
