International Classification:

H01P 9/00
H01P 3/00
H01P 3/06

US Classification:

333156, 333243, 333160

Abstract:

RF and microwave radiation directing or controlling components are provided that may be monolithic, that may be formed from a plurality of electrodeposition operations and/or from a plurality of deposited layers of material, that may include switches, inductors, antennae, transmission lines, filters, hybrid couplers, antenna arrays and/or other active or passive components. Components may include non-radiation-entry and non-radiation-exit channels that are useful in separating sacrificial materials from structural materials. Preferred formation processes use electrochemical fabrication techniques (e. g. including selective depositions, bulk depositions, etching operations and planarization operations) and post-deposition processes (e. g. selective etching operations and/or back filling operations).

Filed:

Jun 1, 2007

Appl. No.:

11/757324

Inventors:

Elliott R. Brown - Glendale CA, US
Rodney F. Sinclair - Thousand Oaks CA, US

International Classification:

H01Q 1/00

US Classification:

342370

Abstract:

Embodiments provide radio-frequency systems that can automatically detect, focus-on, and track objects in the environment without the need for expensive electronic scanning and phase-shifting components. Some embodiments are directed to retrodirective systems including: (1) quiescently broadcast pseudorandom-modulated radiation, such as pseudorandom bit sequences, in the absence of a target, over a field-of-view comparable to the beam solid angle of a single element in the transmit array; (2) a receive antenna element or array, in a desired spatial relationship with respect to the transmit antenna array, that receives reflected pseudorandom radiation from a target; and (3) an electronic signal-processing and feedback channel between the receive and transmit arrays that carries out cross-correlation between the received radiation and the transmitted pseudorandom signals and computes complex correlation coefficients to form a re-transmitted beam. Some embodiments are useful for short-range applications involving small and fast moving targets.

Appl. No.:

12/511065

Assignee:

Physical Domains, LLC - Glendale CA

International Classification:

G01S 13/00

US Classification:

342147, 342175, 342370

Abstract:

Embodiments of the invention are directed to retrodirective radio-frequency systems wherein a transmit antenna array includes at least one row of N transmit elements and a receive antenna array includes at least one row of N receive elements that correspond one-to-one to the transmit elements and wherein the transmit and receive elements are located on spaced planes, and centered about a common axis and located at common transmit distance and a common receive distance, respectively. In some embodiments the one row of transmit and receive elements comprises “n” rows of elements, where “n” is an integer greater than one, thereby forming a two-dimensional array. In some embodiments the total transmit radiation pattern provides an azimuth coverage of 360 degrees. In other embodiments, it may provide less coverage but be operable as independent sectors. In some embodiments, the desired transmit wave form will be identical between all transmit elements of the array, one possible example being pseudo random noise imparted on a sinusoidal carrier.

Inventors:

Elliott Brown - Glendale CA, US

International Classification:

G01S013/72

US Classification:

342090000, 342095000, 342097000, 342189000, 342091000, 342101000

Abstract:

Embodiments of the present invention provide retrodirective noise-correlating radar that include: (1) a transmit antenna array that quiescently transmits random noise; (2) a receive antenna array, in a desired spatial relationship with the transmit antenna array, for collecting the reflected noise from a target; and (3) RF electronic components interconnecting antenna-element pairs between the receive and transmit arrays. In one group of embodiments, the radar automatically transforms the broad pattern from each element of the array (when transmitting or receiving random noise), to a narrow pattern characteristic of the entire array. In a second group of embodiments, a presence of a target and its range are determined quickly by a quasi-coherent build-up of signal in the time or frequency domains. In third group of embodiments a target angle and velocity vector are determined by cross correlation between two or more electronic channels connecting the transmit and receive arrays.
