摘　　要：为解决目标机动导致相关纯方位跟踪算法无法使用的问题,提出一种基于变异数分析的纯方位目标机动辨识方法。利用目标机动前后方位序列回归系数发生变化的特点,结合统计学中变异数分析方法,将纯方位目标机动辨识问题转化为统计学中的变点检测问题,通过假设检验方法判定目标是否机动。该方法直接利用量测的方位序列作为纯方位目标机动辨识的唯一输入,不依赖于纯方位目标跟踪算法解算结果。理论分析与仿真计算验证了该方法的可行性与有效性,为工程应用中提高相关跟踪算法的适用性提供一种技术途径。A bearing-only target maneuvering identification method based on variance analysis is proposed to address the issue of target maneuvering causing the inability of relevant bearing-only tracking algorithms.By utilizing the characteristics of changes in the regression coefficients of the bearing sequence before and after target maneuvering,combined with the analysis of variance method in statistics,the identification problem of bearing-only target maneuvering is transformed into a change point detection problem in statistics.Hypothesis testing is used to determine whether the target is maneuvering.This method directly utilizes the measured bearing sequence as the unique input for maneuvering identification of bearingonly targets,without relying on the tracking algorithm solution results.Theoretical analysis and simulation calculations have verified the feasibility and effectiveness of this method.Provide a technical approach to improve the adaptability of relevant tracking algorithms in engineering application.
