Abstract
A system includes a frequency modulated signal generator, a feed system, and an array of passive antenna elements. The frequency modulated signal generator can be producing a frequency modulated continuous wave signal. The feed system can be coupled to the frequency modulated signal generator for propagating the frequency modulated continuous wave signal. The array of passive antenna elements can be coupled to the feed system and can be configured to be excited by the frequency modulated continuous wave signal. The passive antenna elements can have resonant frequencies that are selected to generate a set of radiative field patterns corresponding to a set of known goal field patterns when the array of passive antenna elements are excited by the frequency modulated continuous wave signal. Related apparatus, systems, techniques, and articles are also described.
