摘要
详细分析了气象雷达中正交通道幅相不平衡对气象回波信号谱估计的影响 ,并给出基本的频域和时域估计法的仿真结果。
In this paper,the influence of amplitude and phase imbalances of I/Q channels on spectrum estimation of weather radar echo signal is analyzed in detail and the simulation results by basic spectrum estimation methods of frequency and time domain is present.
