Abstract

An array antenna configured to be placed at a determined position above the ground surface. The array antenna is assembled by a plurality of unmanned aerial vehicles (UAVs), each UAV carrying one or more antenna elements of the array antenna. The plurality of UAVs configured to create a defined formation at the determined position above the ground and thereby align the one or more antenna elements carried by the UAVs to form the array antenna. The array antenna configured to receive electromagnetic signals reflected from a region of interest, or from one or more objects, within its line of sight.
