摘要: 该文研究了基于发射方向图综合的双基地高频地波超视距雷达发射天线阵互耦、幅度及相位误差模型。根据误差模型的特点，提出一种发射天线阵列误差校正的方法。该方法利用收、发天线之间的直达波信号，采用迭代最小二乘法对发射天线阵误差进行估计。仿真结果验证了该方法的有效性。Abstract: An error model of transmitting array mutual coupling, gain and phase error of the synthetic transmitted beam bistatic HF-Surface Wave Radar (HF-SWR) is investigated in this paper. According to the characteristics of the error model, a transmitting array calibration method is proposed. This method employs the direct signal between receiving antenna and transmitting antenna as calibration sources, and utilizes an iterative Least Square (LS) algorithm to estimate the errors of transmitting array. Simulation results validate the effectiveness of this method.
