摘　　要：为了提高船载高频地波雷达方向角检测的精度,本文提出了一种在时域补偿相位误差的方法。本方法解决了雷达回波信息处理过程中的相参积累过程对误差不断累积的难点,实现了在时域数据的处理过程中对各种原因导致的角度偏差的补偿。本文通过仿真和实测数据分别对频域和时域补偿方法做了分析和比较,研究结果表明,时域补偿方法较频域补偿方法更加准确有效。In order to improve the accuracy of direction angle detection of shipborne high frequency surface wave radar(HFSWR),a phase error compensation method in time domain is proposed in this paper.This method solves the difficulty of continuous error accumulation in the process of coherent accumulation and realizes the compensation of the angle deviation caused by various reasons in the process of time domain data processing.In this paper,the frequency domain compensation method and time domain compensation method are analyzed and compared by simulation and the field data.And the results show that the time domain compensation method is more accurate and effective than the frequency domain compensation method.
