Multidimensional Parameter Estimation Method Based on Sparse Iteration in FDA-MIMO Radar
Leida xuebao, 2018 To accurately identify the range of each target, traditional Multiple-Input Multiple-Output (MIMO) radar techniques not only require designing a shift matrix to describe different range bins but also a large number of snapshots. To alleviate this problem,

Range-Ambiguous Clutter Suppression via FDA MIMO Planar Array Radar with Compressed Sensing
Remote Sensing, 2022 Range-ambiguous clutter is an inevitable issue for airborne forward-looking array radars, especially with the high pulse repetition frequency (PRF). In this paper, a method to suppress the range-ambiguous clutter is proposed in an FDA-MIMO radar with a ...
