摘要
以一维均匀直线阵为模型,利用概率统计的方法分析了随机幅度误差与随机相位误差对于相控阵天线波束副瓣电平的影响,给出了详细的推导过程及波束峰值副瓣电平的闭式表达式,并进行了计算机仿真验证和比较。仿真结果表明,理论公式推导得到的峰值副瓣电平与仿真结果吻合良好。
Based on the model of uniform linear array, the effects of random signal amplitude and phase errors on the sidelobe levels of phased array antenna has been studied, using the theory of probability and statistics. Detailed analytical process and the related closed form equations has been presented. Computer simulation verified the validity of the analytical results.
