To solve the problem of manual selection of regularized parameters in the process of moving target extraction based on iterative tensor High-Order Singular Value Decomposition (HOSVD), Morozov's deviation criterion is used to achieve the adaptive estimation of normalized parameters in moving target detection based on HOSVD. The regularized parameter is selected and adjusted according to the error level, and rapid convergence is realized in the iterative process of the algorithm. Experiments prove that this method greatly reduces the debugging time, and can accurately and completely extract the moving targets.
