| 摘 要： | 针对矢量阵Capon波束形成对阵列误差尤其敏感这一不足,提出了运用洛伦兹锥规划(LCP,Lorentz Cone Pro.gramming)实现导向矢量范数约束来提高波束形成鲁棒性的方法.鉴于矢量水听器声压分量和振速分量对阵列误差敏感程度不同的特点,采用了"双线约束"的策略.将范数约束波束形成转化为LCP形式,通过内点...

| Abstract: | Capon beamformer of acoustic vector sensor array is extremely sensitive to slight array errors.The norm of steering vector is constrained by using Lorentz Cone Programming to improve the robustness.Catering to the characteristic that pressure component and velocity component of an acoustic vector sensor can be influenced in different degrees by array errors,dual-line constraint is adopted.The problem of norm-constraint beamforming can be converted to the form of Lorentz Cone Programming,and solved by interi... |
