摘要

提出了一种基于源定位的矢量脱靶量估计算法。小型天线阵列用于测量目标的运动。一些现代的频谱分析方法,如ESPRIT或MUSIC,可以估计出天线之间的相位差和目标到原点的距离。通过求解由相位差和距离估计组成的一组线性方程,给出了闭式源位置估计。然后,利用从不同样本中估计的所有源位置,形成另一组线性方程,估计未知的矢量脱靶量参数。仿真结果验证了该方法的有效性和可行性。

Estimation of vector miss distance based on source localization
A vector miss distance estimation algorithm based on source localization is presented. A small antenna array is used for measuring the movement of a target. Phase differences among antennas and range from the target to the origin can be estimated by some modern spectral analysis method, such as ESPRIT or MUSIC. A closed-form source location estimate is given by the solution of a set of linear equations constructed from the estimates of phase differences and range. Then, by utilizing all source locations estimated from different samples, another set of linear equations is formed and unknown vector miss distance parameters can be estimated. Simulation results are provided to demonstrate the effectiveness and feasibility of the proposed method.
