摘　　要：本文主要是对以改进空间平滑算法为基础的多信号测向技术进行分析,旨在解决多个相干信号的测向问题。利用这一方法,能简化多信号源测向步骤,并且对测定结果进行仿真分析时,可发现该算法在相干、非相干及混合信号源的信号环境中有较好运用。In this paper, the multi-signal direction finding technique based on the improved spatial smoothing algorithm is analyzed in order to solve the direction finding problem of multiple coherent signals.The direction-finding step of multi-signal source can be simplified by using this method. When the measured results are simulated and analyzed, it can be found that the algorithm has good application in the signal environment of coherent, non-coherent and mixed signal sources.
