Due to too much data, the efficiency of l1 norm-Singular Value Decomposition (l1-SVD) algorithm becomes poor, this paper proposes a Preprocessing l1-SVD algorithm. This method is based on the frequency diversity array of L-type array. Firstly, the search space of the target position is preprocessed to reduce the search space by the inner product of the received data and the perception matrix. Then, l1-SVD algorithm is used to estimate the search space after proposed preprocessing. The simulation results show that the algorithm has better efficiency in the face of large amount of data, and the estimation accuracy is also improved compared with that without processing.
