讨论了宽带恒定束宽阵的形成,介绍了多波束法和Chebyshev公式法这两种设计方法及其优缺点,对所设计的宽带恒定束宽波束形成器进行了计算机仿真,结果表明可较好地实现恒定束宽,抑制了频率畸变。
The formation of broadband constant beamwidth array is discussed. Two design methods of multi-beam method and Chebyshev formula are introduced, and their advantages and disadvantages are introduced. The computer simulation of the designed broadband constant beamwidth beamformer is carried out. The results show that the proposed method is better To achieve a constant beam width, inhibit the frequency distortion.
