| 摘 要： | 通过去掉最小平均相关能量匹配滤波器推导过程中对输出相关峰值的约束条件，定义相关判据,得出畸变不变相关识别综合鉴别函数形式为维纳滤波函数,不仅抗噪能力强,且把非约束匹配滤波器畸变容限大的优点引入其中.模拟结果表明,所设计匹配滤波器畸变容限大、抗噪能力强.

| Abstract: | Constrained condition of output correlation peak value is removed in MACE matched filter,and correlation criterion is redefined. The distortion invariant synthetic discriminant function obtained is wiener filtering function based on correlation criterion to be defined. the filter's sensitivity to input noise and image distortion is reduced. The computer simulation result shows this kind of synthetic filter enhance the distortion tolerance and ability of resisting noise. |

| Keywords: | distortion invariant correlation recognition unconstrained matched filter wiener matched filter |
