摘　　要：针对广义旁瓣对消算法中阻塞矩阵难以构造的问题,提出了一种基于正交基变换的广义旁瓣对消算法。该算法在任意布阵形式下都可以方便地计算出阻塞矩阵,可以大大提高算法适应性。该方法易于在硬件上实现,通过正交基变换数据预处理,可以使波束指向期望方向,通过旁瓣对消算法实现对干扰的抑制。最后,通过理论推导并结合计算机仿真验证了该方法的有效性。In order to solve the problem of constructing block matrix in generalized sidelobe cancellation algorithm,a generalized sidelobe cancellation method based on orthogonal transform algorithm is proposed. The algorithm can easily calculate the block matrix in any form of an array and the adaptability can be greatly improved. The method is easy to implement on hardware and can make the beam pointing to the desired direction by orthogonal transform of data preprocessing. Finally, through theoretical analysis and computer simulation, the effectiveness of this method is verified.
