本文给出了一种基于Gram-Schmidt正交化方法的自适应波瓣置零综合的新算法,此算法采用的是单元零点向量法,它不仅保持了已有算法在波瓣置零综合中的全部优点,而且在对付宽频带干扰及设置较宽的零点凹口时,阵列副瓣电平上升不大。与通常的算法相比,在设置相同的零点凹口情况下,副瓣电平下降了3~5dB。作为应用举例,本文同时给出了新算法与现已报导的RAMONA波瓣置零综合算法的计算机仿真的数值比较结果。
In this paper, a new algorithm based on the Gram-Schmidt orthogonalization is proposed. The algorithm uses the element zero point vector method, which not only keeps the existing algorithm in the zero-setting of the lobe All the advantages, and in dealing with wideband interference and set a wide zero notch, the array side lobe level rise is not big. Compared with the conventional algorithm, the sidelobe level is reduced by 3 ~ 5dB when the same zero notch is set. As an application example, the numerical results of the computer simulation of the new algorithm and the now-reported RAMONA lobe zeroing synthesis algorithm are given.
