Geometric considerations of short-range multistatic SAR based on multi-rotor UAVs for improved spatial resolution

A method on the design of coherent multistatic synthetic aperture radar (SAR) system implemented by short-range radars onboard distributed multi-rotor unmanned aerial vehicles (UAVs) or drones for improved spatial resolution with a single transceiver and multiple bistatic receivers is presented. With high-resolution imaging application in mind, this method is used to derive the locations of all sensors in the system and the limitations of techniques such as this is explored. The theoretical results are confirmed via numerical simulations.
