摘　　要：介绍了机载预警雷达的特点及面临的杂波抑制难题,回顾了杂波仿真的研究历程,在分析机载预警雷达杂波模型及常规空时自适应杂波抑制方法的基础上,提出了一种基于精细化杂波仿真的认知杂波抑制方法。该方法利用数字高程地图数据以及地表覆盖和土地利用数据进行信号级机载雷达杂波反演,补充了均匀杂波样本,提升了非均匀环境下杂波抑制性能,为杂波仿真在机载预警雷达中的应用指出了一种新的途径。最后根据典型机载预警雷达参数和典型地理环境,仿真验证了该方法的有效性。The characteristics of airborne early warning radar and the difficulties of clutter suppression are introduced in this paper.The research process of clutter simulation is then reviewed.On the basis of the analysis of the clutter model of airborne early warning radar and the conventional clutter suppression methods,a cognitive clutter suppression method based on high fidelity clutter simulation is proposed.This method uses digital elevation map data,land cover and land use data to carry out signal level airborne radar clutter inversion.It supplements homogeneous clutter samples,improves clutter suppression performance under heterogeneous environment,and points out a new way for the application of clutter simulation in airborne early warning radar.Finally,according to the typical parameters of airborne early warning radar and geographical environment,the effectiveness of this method is verified by simulation.
