%X 针对电子战飞机(ECAV)编队实施的航迹欺骗容易对雷达网产生虚假空情的问题,提出了一种集中式雷达网鉴别虚假航迹的假设检验(HT)方法。首先,根据航迹欺骗的具体实际,建立了虚假目标量测的误差模型,在此基础上,利用量测数据以及目标状态估计构造了样本的量测误差协方差阵;然后,采用统计分析的方法对误差协方差阵进行假设检验,完成单雷达对航迹真实性的判决;最终,利用M/N逻辑加强判决可靠性,突出雷达网的抗干扰优势。与目前在雷达战术或技术上广泛运用的具有较强试探性的方法相比,HT方法立足理论分析,具有更好的可靠性和可行性,其虚假航迹正确鉴别率能够达到90％以上。<br>A discrimination method based on hypothesis testing is proposed for centralized radar networks to deal with the phantom track deception released by ECAV formation that will easily generate false air intelligence in radar networks. A measurement error model is built for phantom target according to the reality of this kind of deception. Then, a sample covariance matrix is constructed through using the radar measurement and the estimated target state. Hypothesis testing is then made to the matrix by using the statistical analysis method and to complete the sentence of track authenticity of each radar. Finally, the M/N logic is used to enhance the reliability of the judgment, and to highlight the anti？？interference advantages of a radar network. Comparisons with existing widely used methods that are tactical or technique approaches and contain some tentative means show that the HT method is based on theoretical analysis and is reliable and feasible. The correct discrimination rate of the phantom approaches 90％ or more
