多目标环境下的雷达CFAR检测

CFAR Detection Under Multi-target Environments

提出了一种基于对参考单元进行比较筛选的雷达恒虚警 (CFAR)检测方法 ,并对其在不同背景条件下参考单元的分布变化与检测性能进行了分析。结果表明 ,该方法在不降低均匀环境下检测性能的条件下 ,可以明显改善 CA和 OS- CFAR在多目标干扰环境下的检测性能。

A new CFAR detection method based on cell select(CS) is developed and its detection performance is analyzed under different environments. The results indicate that this technique can improve the performance of CA and OS CFAR detection in multi target interference environments without any performance loss in homogeneous environments.
