  • Patent number: 11693112
    Abstract: A continuous wave, frequency diverse array (FDA) Detector, Transmitter, Receiver and/or Method are disclosed. The frequencies can be radio waves or sonic waves. Different frequencies are applied to each transmitter element, to generate transmissions schemes with repeating patterns of constructive interference (e.g. each pattern may be a spiral). The patterns differ (e.g. opposite spiral directions to help determine azimuth, or different spiral rotation speeds to help determine range), to a sufficient extent that from the timing of signal reflected back as a result of each one, the azimuth and/or range of an object can be determined, irrespective of where the object/target is in the field of view. Use of continuous wave transmissions enables lower transmission powers and/or avoids requiring an expensive beam-steering transmitters or receivers.
