A Model-Free Approach To Distributed Transmit Beamforming

This paper presents a model-free solution to distributed transmit beamforming using mobile agents. Each agent is equipped with an antenna and the agents represent the individual elements in an antenna array. The agents are tasked to coordinate their relative location, phase offsets, and amplitude to construct a desired beam-pattern. As a prospective solution, we propose a model-free optimization algorithm based on real-time feedback that does not require a model that maps the control parameters (relative location, phase offsets, and amplitude) to a radiation pattern. We evaluate the performance of proposed approach for different motion constraints. Numerical results are presented to validate the theory.
