摘　　要：提出了一种利用Unitary ESPRIT(UESPRIT)算法提取任意源的信号参数的方法,结合反向射线追踪技术以及城市电子地图便能对目标源进行三维定位。推导分析了如何提取任意目标源的信号参数,简要概述了反向射线追踪技术。以高斯脉冲源为例做了一系列数值论证,数值结果证明:提出的方法可以同时高效的估计视距源和非视距源。In this paper,a parameter estimation method for arbitrary signal source based on the unitary ESPRIT algorithm is proposed. Arbitrary 3-D source can be located by that method together with the back ray tracing technique and the city electronic maps.First,the formulas and algorithm for extracting signal parameters from the arbitrary source is deduced and analyzed. Then,a brief sketch of the back ray tracing technique is made. In the end,Gaussian pulse istaken as an example. Numerical results demonstrate that ...
