2-D MUSIC method has been presented to jointly estimate range and DOA of narrowband near field signals. However, this approach is impractical on enormous application situations such as underwater source detection. Sparsity-based IAA are able to work well with few snapshots (even one). Two-dimensional version of IAA is proposed to estimate 2-D range and bearing information of narrowband near-field sources with few snapshots. In the case that snapshots are abundant, both 2-D MUSIC and 2-D IAA do well in estimating range and DOA. However, when it comes to a few snapshots, 2-D IAA performs much better than 2-D MUSIC. Computer simulation results by MATLAB validate the efficacy of 2-D IAA algorithm with few snapshots.
