摘要
在讨论机载雷达地面杂波的基础上,利用最大熵估计法对机载雷达杂波进行抑制,并引入了cholcsky分解快速算法求解最大熵谱的AR模型参数。计算机模拟表明,基于最大熵谱估计的机载雷达杂波抑制技术有很高的谱分辨率,不仅能跟踪主杂波的频率位置而且能跟踪其谱宽度,因而具有较为满意的杂波对消化与改善因子。
Based on discussing the ground clutter for airborne radar,the clutter issupressed by using the MEM(Maximum Entropy Method).The results of simulation showthat,the technique of clutter suppression has high resolution of spectrum. It can trace theDoppler location and width of main clutter spectrum,and has a satisfying clutter cancellationration.
