Detection of a signal in linear subspace with bounded mismatch [PDF]
, 2006 We consider the problem of detecting a signal of interest in a background of noise with unknown covariance matrix, taking into account a possible mismatch between the actual steering vector and the presumed one.

Transmit Beamspace Design for Bistatic MIMO Radar With Improved Angle Estimation
IEEE Access, 2019 The energy dispersion of traditional bistatic multiple-input multiple-output (MIMO) radar severely degrades the angle estimation performance. To overcome this limitation, we propose to design the transmit beamspace matrix and apply the design result to ...
