摘要
针对阵列误差是制约矢量传感器阵列波束形成系统性能的重要因素,在提出用运动学中的"广义欧拉角"来描述阵元姿态误差的基础上,建立了阵列误差的高斯扰动模型,进而推导了基于矢量传感器阵列的实际波束响应的理论表达式,并深入分析了各类随机阵列误差对系统性能的影响,得出若干条颇有意义的结论,最后给出了仿真实验验证结果。
Array errors are important factors that restrict the performance of the vector-sensor array beam-forming system.On the basis of taking use of the ＂Generalized Euler Angle＂ from kinematics to describe the attitude error of the array elements,Gauss Perturbation Models of array errors were established.And then,the theoretical expression of real beam-response of the vector-sensor array was deduced.Moreover,the influence of every kind of random array error on the performance of the system was also analyzed in-depth,and some pieces of useful conclusions were obtained.Finally,the result of simulation experiment proves the legitimacy of theoretical analysis.
