摘 要: | 针对雷场低空运动多目标方向角估计中,现有算法需要设置立体传感器阵列,且估计精度还不能满足实战化要求等问题,提出了基于圆形传感器阵列的运动多目标二维波达方向估计方法;该方法用向量来表示方向角,采用独立分量分析算法,并结合波束形成算法,实现运动多目标方向角估计;场地实验表明:该方法能够准确地识别运动多目标的数目,其二维波达方向估计精度比基于小波加权的相关时延算法要好,为提高雷场运动多目标识别率和定位精度提供了新的技术途径。

2D-DOA Estimation of Moving-Target Based on Round Sensor Array |

Abstract: | For moving multi-target direction angle estimation of the minefield,the exiting algorithms need to set up the three-dimensional sensor array,and the resolution is not good enough.A new method was proposed to estimate the 2D-DOA of the moving multi-target based on the round sensor array.The method combined with the independent component analysis algorithm and the beam-forming algorithm,using vector to represent the direction angle,which can estimate the 2D-DOA of the targets.The field experiments show that the method plays better than the cross correlation algorithm of 2D-DOA estimation,and provides a new way for improving the minefield movement targets identification and positioning precision. |
