Abstract: A radar cloaking apparatus configured for positioning on a radar target and corresponding methods are provided. The radar cloaking apparatus comprises a radio signal emitter and computational circuitry. The computational circuitry is configured to cause the radar cloaking apparatus to at least reference a model encoding scattering properties of the radar target; determine a predicted reflection signature of the radar target from a selected interrogation angle based at least in part on the model encoding the scattering properties of the radar target; and cause transmission, by the radio signal emitter, of a cloaking radio signal along the selected interrogation angle. The cloaking radio signal is actively generated based on the predicted reflection signature of the radar target shifted in phase such that the cloaking radio signal is configured to destructively interfere with a reflected signal formed by an interrogating radar signal scattering off of the radar target.
