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,

Geostationary Orbital Targets Imaging Based on Ground-Based Multiple-Input Multiple-Output Radar

Remote Sensing
Compared with the Earth’s surface, geostationary orbital (GEO) targets are relatively static, which makes it difficult to obtain two-dimensional radar images when the radar is ground-based without movement.
