中文摘要:
      为进一步提高超波束形成(Hyper Beam Forming,HBF)算法的性能,在传统的HBF基础上提出一种改进的HBF(Improved Hyper Beam Forming,Im-HBF)算法。将基于半阵指向性函数高阶运算修正到基于全阵指向性函数的高阶运算。仿真结果表明,Im-HBF算法具有更窄的主瓣,并且对端射来波信号栅瓣抑制能力更强,进一步提高了对目标的检测能力。同时,Im-HBF算法对指数n具有更为广泛的适用性,当指数n>2时也能获得优于常规波束形成(Conventional Beam forming,CBF)的波束性能。
英文摘要:
      In order to achieve greater performance of hyper beamforming algorithm, this paper proposes an Improved Hyper Beam Forming (Im-HBF) method based on the higher order operation of whole array instead of half array. Simulation results show that the Im-HBF method can get greater reduction of beam width and grating lobe and better detection performance. The Im-HBF method can be satisfied with the index of n in generalize, although the index of n>2 also could get better performance than Conventional Beam forming (CBF).
