基于一维辅助波束的自适应-自适应波束形成

Adaptive-Adaptive Beamforming With One-Dimensional Auxiliary Beams

为了避免面阵自适应-自适应波束形成方法在构建二维辅助波束时需要对干扰入射角进行二维搜索,提出了基于一维辅助波束的面阵自适应-自适应方法.该方法首先估计出干扰的一维空间角并形成一维空间辅助波束,再将辅助波束同主波束一起进行自适应波束形成处理来抑制掉干扰.由于只需估计干扰的一维空间角,因而对干扰入射角的搜索计算量大大降低,适合于工程实现.仿真结果证明了方法的有效性.

In order to avoid two-dimensional search for the incidence angle of jamming while constructing two-dimensional auxiliary beams in terms of the method of planar array adaptive-adaptive beamforming, this paper proposes an adaptive-adaptive beamforming algorithm of planar array based on one-dimensional auxiliary beams. This novel algorithm estimates one-dimensional spatial angle of jamming and forms one-dimensional spatial auxiliary beams, and then, implements the adaptive beamforming processing to the auxiliary beams together with the main beams for suppressing jamming. The computational complexity of searching for the incidence angle of jamming can be reduced greatly, as it only needs to estimate one-dimensional spatial angle of jamming, which is applicable to engineering implementation. Simulation results could prove the proposed algorithm to be available.
