Optimizing Combined Transmit-and-Receive Coherent Distributed Arrays

Abstract

In the presented work, a model for a combined transmit-and-receive coherent distributed array system is considered. The system model describes a pair of distributed arrays, a transmit array and a receive array, that are defined as aperiodic volumetric arrays with cubic array volumes. Total gain for a combined transmit-and-receive coherent distributed array is labeled coherent communication gain (CCG), and a general expression for CCG is given. The general expression can accommodate various propagation models as well as directional elements. Various distributed array systems are simulated using different parameters and the corresponding CCG is calculated. Optimization methods are explored for the purpose of improving the CCG of a distributed array system by adjusting the positions of the array nodes and the beam angle of the transmit array. Simulations are conducted to test and compare the improvements in system gain and the typical node displacement resulting from the application of optimization techniques.
