Abstract: Multiresolutional signal processing has been employed in image processing and computer vision to achieve improved performance that cannot be achieved using conventional signal processing techniques at only one resolution level ［1，2，5，6］．In this paper，we have associated the thought of multiresolutional analysis with traditional Kalman filtering and proposed  a new fusion algorithm based on singular Sensor and Multipale Models for maneuvering target tracking．

Key words: multiresolutional analysis, wavelet transform, Kalman filtering, Target Tracking
