N2 - In this paper, the problem of joint hot and cold clutter mitigation in the context of transmit beamspace (TB)-based multipleinput multiple-output (MIMO) radar is studied. The TB-based MIMO radar enables special spatio-temporal structure and low rank of clutter covariance matrices. To efficiently mitigate the hot clutter such as terrain scattered multipath jamming concentrated in the sector-of-interest and the enhanced cold clutter due to transmit energy focusing, we resort to three-dimensional (3D) space-time adaptive processing (STAP) technique. A new 3D STAP method is proposed, which significantly reduces the computational complexity. We show from interference mitigation perspective that the TB-based MIMO radar enables superior output signal-to-interference-plus-noise ratio to that of its traditional MIMO radar counterpart.
