Abstract: In an embodiment, an antenna includes a one-dimensional array of antenna cells, a signal feed, and signal couplers. The antenna cells are each spaced from an adjacent antenna cell by less than one half a wavelength at which the antenna cells are configured to transmit and to receive, are configured to generate an array beam that is narrower in a dimension than in an orthogonal dimension, and are configured to steer the array beam in the dimension. And the signal couplers are each configured to couple a respective one of the antenna cells to the signal feed in response a respective control signal having an active level. For example, the antenna cells can be arranged such that a straight line intersects their geometric centers.

Abstract: 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 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. 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. To reduce aliasing, such an antenna subsystem can be operated to filter, spatially, a receive beam pattern generated by the receive antenna with a transmit beam pattern generated by the transmit antenna.

Abstract: An embodiment of a radar subsystem includes at least one antenna and a control circuit. The at least one antenna is configured to radiate at least one first transmit beam and to form at least one first receive beam. And the control circuit is configured to steer the at least one first transmit beam and the at least one first receive beam over a first field of regard during a first time period, and to steer the at least one first transmit beam and the at least one first receive beam over a second field of regard during a second time period.

Abstract: An embodiment an antenna unit of an antenna array includes a signal coupler, a phase-shifting modulator, and an antenna element. The signal coupler has a first input-output port, a second input-output port, and a coupled port. The phase-shifting modulator is coupled to the coupled port of the signal coupler, and the antenna element is coupled to the phase-shifting modulator via a connection remote from the signal coupler, or via an isolated port of the signal coupler. The phase-shifting modulator is configured for both relatively low signal loss and relatively low power consumption such that the antenna array can have significantly lower C-SWAP metrics than a conventional phased array while retaining the higher performance metrics of a conventional phased array.

Abstract: 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.

Abstract: An embodiment of an antenna array includes a transmit antenna and a receive antenna. The transmit antenna has, in one dimension, a first size, and has, in another dimension that is approximately orthogonal to the one dimension, a second size that is greater than the first size. And the receive antenna has, in approximately the one dimension, a third size that is greater than the first size, and has, in approximately the other dimension, a fourth size that is less than the second size. For example, such an antenna array, and a radar system that incorporates the antenna array, can provide a high Rayleigh resolution (i.e., a narrow Half Power Beam Width (HPBW)) with significantly reduced aliasing as compared to prior antenna arrays and radar systems for a given number of antenna-array channels.
