[en] This paper deals with the design of transmit probing
signal under the trade-off between good target discrimination
(low cross-correlation beam pattern) and beam pattern design
(desired auto-correlation beam pattern) in a Multiple-Input-
Multiple-Output (MIMO) radar configuration. The quartic optimization
problem, with a finite alphabet constraint on the
probing signal and using Quadrature Phase Shift Keying (QPSK)
in a multiplexed antenna system, is solved through a Fourier
series approximation of the desired beam pattern by exploiting
a block circulant property of the transmit signal matrix. The
mean square error between an ideal and the proposed crosscorrelation
beam pattern is -35 dB enhancing the attractiveness
of the proposed approach.
