摘要/Abstract

摘要： 在数字阵列雷达中,通道失配对低旁瓣波束形成、输出信号信干比以及抗干扰性等多项指标产生严重影响。为了校正误差,通道均衡技术逐渐应用到阵列误差校正上并得到了迅速发展。根据均衡器权系数求解方式将当下通道均衡技术分为时域最小二乘拟合法、频域最小二乘拟合法以及傅里叶变换法。重点分析各方法的主要原理以及研究难点,并综合比较各类方法的优缺点,最后总结了数字阵列雷达通道均衡技术在未来发展中需要攻克的难点。

Abstract: In digital array radar (DAR), channel mismatch has a serious impact on many indicators such as low sidelobe beamforming, signal to interference ratio of output signal and anti-interference. To correct the error, the channel equalization technique is gradually applied to the array error correction and has been rapidly developed. The current channel equalization techniques are divided into time domain least square fitting method, frequency domain least square fitting method and Fourier transform method according to the equalizer weight coefficient solving method. The main principles and difficulties of each method are analyzed emphatically, and the advantages and disadvantages of various methods are compared. The difficulties of the digital array radar channel equalization technique in future development are summarized.

Key words: digital array radar, channel mismatch, channel equalization, equalization filter, weight coefficient, error correction
