摘　　要：该文采用最大相关熵准则(MCC)对平行因子分析算法中基于三线性最小二乘(TALS)迭代准则的目标函数进行了修正,推导出适用于脉冲噪声环境的韧性平行因子分析(PARAllel FACtor,PARAFAC)算法(MCC-PARAFAC算法),并将该方法应用于双基地MIMO雷达系统目标参数估计中。MCC-PARAFAC算法能够抑制脉冲噪声的影响,具有较好的估计性能,并且能够实现自动配对。仿真实验验证了算法的有效性。By employing the Maximum Correntropy Criterion （MCC） based cost function in PARAllel FACtor （PARAFAC）, the MCC-PARAFAC algorithm is deduced, which can be utilized for the parallel factor under impulsive noise environments. The MCC-PARAFAC algorithm is applied to parameter estimation in bistatic MIMO radar under impulsive noise environment. The proposed method can suppress the impulse noise interference and has better estimation performance. Furthermore, the estimated parameters are automatically paired without the additional pairing method. Simulation results verify the effectiveness of the proposed method.
