Based on inverse filtering technique, a method of rotating invariance matched filtering correlation recognition is proposed in this paper. Using cascade modified filter method, the optimization of transmitted matched correlation peak intensity to transmitted input energy can be realized. And so the sharpness of correlation peak is improved greatly. The computer simulation results show that for the rotating image, the rotating invariance matched filtering correlator of rotating 0°～32° with 4° interval proposed in this paper possesses good correlation invariance recognition performance, especially the target recognition can still be successfully in progress under the case of partly input target image.
