5. Conclusion
In this paper, we formulated the problem of target localization in MIMO radars in sparse representation framework.The proposed method solves the sparsity-aware ML estimation of target’s position by utilizing TDOA and AOA measurements and employs an iterative blockwise technique to reduce complexity and enhance accuracy, simultaneously. Then we proposed a dictionary learning based method to mitigate the off-grid mismatch due to discretization. The effectiveness of the proposed method was verified by simulation results.
