Abstract

A vector miss distance estimation algorithm based on source localization is presented in this paper. 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.
