In this paper, we consider a multiple-input-multiple-output (MIMO) detection problem with M
widely spaced transmit antennas and L widely spaced receive antennas, and we study the
problem of designing the signal waveforms transmitted by each source node under non-
Gaussian target scattering and temporally correlated Gaussian clutter. Two figures of merit
are investigated for space-time code (STC) optimization under a semidefinite rank
constraint: 1) the lower Chernoff bound (LCB) to the detection probability for fixed probability …

We consider a multiple-input multiple-output (MIMO) detection problem with widely-spaced
antennas at both the transmitter and the receiver, and we assume that target scattering is
modeled as an exchangeable and unitarily-invariant process. We illustrate optimal signal
design (ie, space-time coding) at the transmitter for two criteria, ie the lower Chernoff bound
(LCB) to the detection probability for fixed probability of false alarm and the mutual
information (MI) between the observations and the target scattering matrix, under a semi …
