摘要
文章对机载预警雷达海面目标CFAR检测门限参数生成过程进行了深入研究,分析其存在的问题。通过对该参数计算过程重新规划,提出了基于波束指向的CFAR检测门限自适应生成方法,通过将当前波束指向上的地理距离段及探测区域距离段的有效融合,动态计算海面目标CFAR检测参数,使得其更贴近实际应用场景需求及操作者的意图。
In this article, the process of generating threshold parameters for CFAR detection of airborne early warning orienting radar sea surface targets is researched deeply,and some existing problems are advanced. By re-planning the calculating process,a method of generating threshold parameters for CFAR detection adaptively based on the current beam is proposed. This method can calculate the threshold parameters for CFAR detection of sea surface targets dynamically through the effective merge of geographical distance segments orienting current beam with that of the detecting zone, thus the parameters can be more close to the requirements of actual application scenarios and the intention of the operator.
