摘　　要：为了提出一种定量表述雷达假目标仿真精度的方法,依据雷达图像目标检测的辐射分辨率理论,沿用指定图像强度计算错误概率的分析方法,给出了目标对比、独立视数与错误概率的关系,进而解析了真假目标雷达散射截面差值与目标正确发现概率的定量关系。理论分析表明,雷达假目标仿真精度的设计参数应选择为不大于3 dB。Based on the radiation resolution, a description method of imitation precision was presented for artificial radar target. Using the error detection probability calculation method for a given imagery intensity, the relationship between target contrast, independent looks and error probability was discovered. Finally the detection probability dependence on the RCS difference between true and false targets was analyzed. The theoretic results indicate that imitation difference of artificial radar targets should be less than 3 dB,
