Adaptive wireless beamforming for swarm array
2018
In this paper, we present a novel adaptive wireless beamforming technique for swarm array (SA). The array elements are airborne self-organized mini-drones that act as RF repeaters between the target and the designation. The repeaters amplify and up convert the received signal and transmit to the destination at slight different frequencies among them to avoid self-interference. The receiver will separate the mixed signal to each RF channel through a filter bank, down convert to baseband, amplified, digitized and send to a PC or FPGA based beamformer to recover the desired signal. System principles, simulation study on link budget and SA noise model, and the repeater design are presented.
