Fully Reconfigurable Power Amplifier Array Design

As more radar and wireless communication systems access the electromagnetic spectrum, interference becomes more common. To increase robustness to interference, a fully reconfigurable array topology and optimization methodology is presented which can enable spectral mobility through live impedance tuning and signal equalization. Pulse-to-pulse optimizations allow efficiency maximization while maintaining array pattern integrity. This array is compatible with advanced digital beamforming techniques such as directional modulation, is highly modular, and is designed for forward compatibility. A demonstration of the proposed optimization for dual-function radar-communications is presented in simulation with a linear sixteen-element array, but it is easily scalable to larger arrays.
