Here we consider a corner target positioning problem under the condition of unknown walls' positions using time‐division multiple‐input‐multiple‐output (MIMO) radar. Firstly, we propose an estimation algorithm for the walls' positions using the Back‐Projection (BP) imaging algorithm. Then, after obtaining the BP image of target, we extract the focus regions produced by different multipaths. Finally, we obtain the position of the target based on the extracted walls' positions and the focus regions. Simulations and experiments results validate the proposed algorithm.
