Particle swarm optimization of minimum-redundancy MIMO arrays

Minimum-redundancy multiple-input multiple-output (MR-MIMO) antenna arrays - a class of thinned arrays - are introduced. The concepts of convolution array and correlation array are used for data processing required for radar applications but also for optimization of the element distribution in such arrays. An upper bound for the achievable thinning rate is estimated. Particle swarm optimization (PSO) is applied to optimize the element distribution of some linear, monostatic MR-MIMO arrays with up to 12 elements.
