Visible image-based detection and tracking system has been used for controlling the firing system to fire impending antiship missile. In this paper, the surface target image is segmented by computing the difference of two adjacent images and then by filtering with wavelet transform. Target detection and tracking is fulfilled by computing the target figures′ consistency and by its centroid linear regression. Experimental results show that this method can be used to detect the antiship cruise missile whose gray scale is very close to the environment and also used widely for other kinds of missile or airplane detection.
