| 摘 要： | 提出了一种精确控制旁瓣和抑制干扰的自适应波束形成算法。它是通常的最小方差无畸变（MVDR）波束形成算法的改进形式，使阵列输出信号功率最小的同时，保持目标信号方向的无失真响应，并且严格保证旁瓣低于某一给定值，抑制干扰。在仿真过程中，充分应用了二阶锥规划（second—order cone programming）算法，并与MVDR波束形成算法进行比较，验证了方法的正确性，同时研究了该算法的稳健性。

| Abstract: | A new approach to adaptive beamforming with sidelobe control is developed.The proposed beamformer represents a modification of the popular minimum variance distortionless response(MVDR) beamformer.It minimizes the array output power while maintaining the distortionless response in the direction of the desired signal and a sidelobe level that is strictly guaranteed to be lower than some given(prescribed) threshold value.The modified MVDR method is obtained by using second-order cone programming approach.It is considered to be correct and robust compared with the MVDR method. |
