摘要

针对阵列雷达系统中自适应波束形成技术计算复杂度高的问题，提出了一种两级加权低复杂度自适应波束形成方法。首先，将均匀线性阵列划分为子阵列，每个子阵列具有相同的元素。然后通过使用第一级加权补偿延迟来叠加子阵列中的每个阵列元素接收到的所需信号。最后，利用二级加权对干扰信号和噪声进行抑制，得到理想的输出信噪比。仿真结果验证了该方法的有效性和可靠性。

A Two-Level Weighted Low-Complexity Adaptive Beamforming Method

Aiming at the problem of high computational complexity of adaptive beamforming techniques in array radar systems, a two-level weighted low-complexity adaptive beamforming method is proposed in this letter. First, the uniform linear array is divided into subarrays and each subarray has the same elements. The desired signal received by each array element in the subarray is then superimposed by compensating for the delay using a first level weighting. Finally, the interference signals and noise are suppressed using a second level weighting to obtain the ideal output signal to interference plus noise ratio. Simulation results verify the effectiveness and reliability of the proposed method.
