摘要
文章研究了等间距线列阵宽带恒定束宽波束形成器的实现原理。给出了利用窗函数获得实现恒定束宽所需子频带加权矩阵的方法。利用获得的加权矩阵 ,构建了恒定束宽频域算法模型 ,并通过计算机仿真验证了其有效性。
This paper studies the realization theory of beamformer with frequency invariant beam pattern of equally spaced linear arrays. It also submits the method to obtain the sub-frequency band weighting matrix for shaping frequency invariant beam pattern by means of window functions, and presents frequency-domain arithmetic model that has used the weighting matrix and affirms its validity through computer simulation.
