Abstract
In some examples, an FMCW radar array includes a housing, a transmit array comprising a plurality of transmit antenna elements configured to output an FMCW transmit beam, a receive array comprising a plurality of receive antenna elements, and a slotted choke disposed between the transmit array and the receive array. The transmit array and the receive array may be mechanically coupled to the housing. In some examples, the slotted choke comprises a plurality of slots having dimensions selected to provide cancellation of electromagnetic radiation from the frequency modulated continuous wave transmit beam to reduce a magnitude of radiation from the transmit array to which the receive array is indirectly exposed.
