Widely distributed MIMO radar beamforming for detecting targets with slow RCS fluctuations
In a widely distributed MIMO radar, the transmitters and the receivers are distributed so that they see a target from different aspects. The scattering from the target is therefor...

Bound-ratio minimization of filter bank frames by periodic precoding
Frame (upper and lower) bound ratio is a key factor of numerical stability of frame systems. While tight frames, of which the minimal ratio 1 is achieved, are much preferred in ma...
