一种快速自适应宽频带多通道相位补偿方法

A Fast Adaptive Phase Compensation Method of Wide Band and Multi-channel

文章提出了一种快速自适应宽频带多通道相位补偿方法,通过对通道间的相位误差进行快速实时补偿校正,消除通道间个体差异和环境影响等因素造成的相位误差。实验结果表明,该种方法能实现对2~18GHz全频段百毫秒以内实时快速相位补偿校正,显著提高了宽频带多通道比相体制接收机对新体制雷达实时快速截获能力。

This paper proposes a fast adaptive broadband multi-channel phase compensation method, which can eliminate the phase errors caused by factors such as individual differences between channels and environmental influences by quickly compensating and correcting the phase errors between channels in real time. The experimental results show that this method can realize real-time fast phase compensation correction within 100 milliseconds in the full frequency range of 2-18 GHz, and significantly improve the real-time fast interception capability of the broadband multi-channel phase-comparison system receiver for the new system radar.
