Publication number: 20240183937Abstract: In an embodiment, an antenna subsystem includes a sparse receive antenna and an electronically steerable transmit antenna. The sparse receive antenna includes an array of electronically steerable receive elements each configured to receive a respective signal having a wavelength and each spaced apart from each adjacent one of the receive elements by a respective first distance that is more than one half of the wavelength, has an aperture, and is configured to generate a receive beam pattern. And the electronically steerable transmit antenna includes an array of transmit elements each configured to radiate a respective signal having the wavelength and each spaced apart from each adjacent one of the transmit elements by a respective second distance that is less than one half of the wavelength, has an aperture that is significantly smaller than the aperture of the sparse receive antenna, and is configured to filter, spatially, the receive beam pattern.Type: ApplicationFiled: December 5, 2023Publication date: June 6, 2024Applicant: Echodyne Corp.Inventors: Nicholas K. Brune, Muhammad Rameez Chatni, Tom Driscoll, Jonathan R. Hull, John Desmond Hunt, Christopher L. Lambrecht, Nathan Ingle Landy, Milton Perque, Charles A.

Patent number: 10601130Abstract: An embodiment of an antenna comprises an array of antenna elements arranged in groups of antenna elements adjustably coupled to respective reference waves. A multiplicity of patterns of antenna coupling settings are defined, each of which gives rise to a main lobe which points the antenna in a particular direction, each pattern also giving rise to respective side lobes. First and second such patterns may point the antenna in the same direction but with non-identical side lobes. In this way the clutter level from the side lobes relative to the main lobe is much smaller than would be the case if one of the patterns were employed both for transmitting and receiving. Alternatively, the first and second patterns may be used in quick succession both for transmitting, or used in quick succession both for receiving. The antenna may also switch rapidly between patterns where the main lobe points in a different direction in each pattern, allowing dithering of the beam or rapid switching between scanning and tracking.Type: GrantFiled: July 20, 2017Date of Patent: March 24, 2020Assignee: Echodyne Corp.Inventors: Tom Driscoll, William F. Graves, Jr., John Desmond Hunt, Nathan Ingle Landy, Christopher L. Lambrecht, Milton Perque, Robert Tilman Worl
