Antenna array design in MIMO radar using cyclic difference sets and simulated annealing

In this paper, the antenna array design problem in minimum redundancy MIMO radars is addressed, which seeks to maximize the virtual array aperture for a given number of transmitting and receiving (Tx/Rx) elements. A hybrid optimization method combining cyclic difference sets (CDSs) with simulated annealing (SA) is proposed for the optimal design of Tx/Rx antenna arrays. Numerical results are also presented, showing large variety in array configurations and notable improvement in the spatial resolution.
