摘要
军用雷达经常在存在电子干扰的环境中作战,如果天线阵列方向图能在干扰方向形成零陷,将大大提高雷达整机性能。本文分别研究了天线单元的馈电幅相控制、幅度控制、相位控制算法,给出了仿真结果。这些算法具有思路简单、计算速度快、稳定性好的特点,适用于自适应天线阵列,对相控阵调零算法亦有参考价值。
Military radars are often used under electromagnetic interferences. If the pattern forms nulls in the directions of interference, the radar performance will be improved greatly. Three methods for pattern null steering, amplitude-phase perturbation, amplitude perturbation, phase perturbation, are presented and analyzed through simulations in the paper. These methods are simple, fast and steady, and are fit for adaptive antenna array. They may be a reference in phased-array null steering.
