一種利用幅值抖動形成陣列零陷的方法

Array Pattern Nulling by Amplitude-Only Perturbations

  • 摘要: 該文提出了一種在陣元關(guān)于陣列中心對稱的線陣中利用幅值抖動形成零陷的方法,該方法能夠在多個強(qiáng)干擾源方向或在較寬的范圍形成深度零陷, 而不影響主瓣, 同時克服了傳統(tǒng)幅值抖動方法零陷深度不足、旁瓣水平高的缺陷。該方法使得移相器只需用來控制主瓣方向, 加快了響應(yīng)速度。仿真表明,該算法實(shí)現(xiàn)簡單,且其性能可與復(fù)權(quán)值控制方法的性能相比。同時由于幅度抖動的對稱性, 在中心對稱的線陣中只需要天線數(shù)目一半的衰減器, 成本較低。
