Real-time and near-real-time acquisition systems for measuring aliasing in small arrays based on crystal microstructures

Planar and volumetric arrays are for their ability to mitigate aliasing in direction of arrival (DOA) estimation using the multiple signal classification (MUSIC) algorithm. The arrangements of elements within the array are based on classic array topologies and lattice configurations native to crystal microstructures. Both an eight channel switched configuration for near-real-time measurements and a simultaneous eight channel acquisition system for real-time evaluation of DOA estimations are used to evaluate these different antenna arrays for both static and motion-dynamic scenarios.
