Abstract
A method of optimizing BLoS communications between a first asset and a second asset using at least one of atmospheric troposcatter and ducting signal propagating phenomena includes transmitting a plurality of test signals from multiple antenna elements of the first asset into the atmosphere. At least a portion of the test signals are received at multiple antenna elements of the second asset. The second asset is configured to calculate a gain and phase shift of the channel between each transmitting and receiving antenna element, calculate optimized antenna weights for the transmitting and receiving antenna elements, and estimate a communication channel coherence time and coherence bandwidth. These parameters may be transmitted to the first asset and applied thereto for optimizing communications between the first and second assets.
