摘　　要：针对多输入多输出(Multiple-InputMultiple-Output,MIMO)雷达信号调制识别存在的问题,提出一种循环谱和二维最大散度差(Two-DimensionalMaximum Scatter Difference,2DMSD)线性判别分析相结合的新方法。首先对典型MIMO雷达信号进行循环谱变换,在此基础上,利用2DMSD线性判别分析对上述二维图像进行特征提取,最终达到调制识别的目的。仿真结果表明,在低信噪比时,该方法仍然具有较高的识别率。To correctly classify MIMO radar signals,a new method based on Cyclic spectrum combined with the two-dimensional maximum scatter difference（2DMSD）linear discriminant analysis is presented in this paper. First,the new method calculated the cyclic spectrum of the signal.Then,the2DMSD is used to extract features as the last recognition characteristic. Simulation results show that this method is effective while the the signal-to-noise ration（SNR）is low.
