摘要
提出一种实时船舶雷达波束补偿方法,通过高效的坐标变换与姿态补偿算法,实时补偿船舶姿态变化对雷达波束指向的影响,从而提升雷达对目标的角度测量精度。采用查表法计算三角函数,并结合优化的矩阵乘法器流水线设计,有效降低硬件资源消耗,实现高效的实时计算。实验结果表明,姿态补偿后雷达的方位和俯仰精度大幅提高,系统性能得到显著提升。
This paper proposes a method of real-time beam compensation for shipborne radars,which utilizes efficient coordinate transformation and attitude compensation algorithms to dynamically correct the impact of ship attitude changes on radar beam pointing.This enhances the accuracy of angular measurements for target detection.The system uses a lookup table method for trigonometric function calculations and incorporates an optimized matrix multiplier pipeline design,effectively reducing hardware resource consumption and achieving efficient real-time computation.Experimental results demonstrate that the attitude compensation significantly improves both azimuth and elevation accuracy,thereby substantially enhancing the overall performance of the radar system.
