摘要
本文研究了慢门限恒虚警处理和快门限恒虚警处理算法,针对慢门限恒虚警电路模型使用对数减法来代替除法运算以提高效率;针对快门限恒虚警处理电路模型存在的边缘效应问题,采用双侧单元平均选大的解决方案,使雷达检测系统始终处于恒虚警状态。
Slow and fast thresholds CFAR processing algorithms are studied.Aiming to slow threshold CFAR circuit model,logarithmic subtract is used to improve efficiency instead of division operation.To the edge effect problem exists in fast threshold CFAR processing circuit model,the solution of selecting the maximum in average from both side units is adopted.And this makes the radar detection system be in constant false alarm.
