Sparse Scenario Imaging for Active Radar in the Forward‐Looking Direction

open access: yesMathematical Problems in Engineering, Volume 2014, Issue 1, 2014., 2014
The resolution of multiple targets at the same range cell but different angles in the forward‐looking direction is of great trouble for active radar. Based on compressive sensing (CS) framework, a sparse scenario imaging approach using joint angle‐Doppler representation basis is proposed, which employs multisensor and single‐receiver channel hardware ...
