摘要: 該文研究了基于發(fā)射方向圖綜合的雙基地高頻地波超視距雷達(dá)發(fā)射天線陣互耦、幅度及相位誤差模型。根據(jù)誤差模型的特點(diǎn)，提出一種發(fā)射天線陣列誤差校正的方法。該方法利用收、發(fā)天線之間的直達(dá)波信號(hào)，采用迭代最小二乘法對(duì)發(fā)射天線陣誤差進(jìn)行估計(jì)。仿真結(jié)果驗(yàn)證了該方法的有效性。

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. -
