| 摘 要： | 本文针对非均匀杂波,利用球不变随机矢量(SIRV)建立了机载多输人多输出(MIMO)雷达杂波模型.基于杂波协方差矩阵不满秩,提出了一种用于估计归一化杂波协方差矩阵的修正渐近最大似然(MAML)算法及其广义似然比检测器,即修正渐近广义似然比检测器(MAGLRT).仿真试验结果表明,在非均匀的杂波下,MAGLRT较常规高斯...

| Abstract: | A model of clutter of airborne multiple-input multiple-output(MIMO) radar in nonhomogeneous environment is formulated based on spherically invariant random vectors(SIRV).The modified asymptotical maximum likelihood(MAML) method is proposed to estimate the singular normalized covariance matrix of clutter and the modified asymptotical generalized likelihood ratio test(MAGLRT) detector is developed based on it.Simulation results reveal that the MAGLRT detector has a great advantage over conventional Gaussian m... |
