US Patent:

54423619, Aug 15, 1995

Filed:

Jan 21, 1994

Appl. No.:

8/184535

Inventors:

Steven J. Peters - Renton WA
Kenneth G. Voyce - Bellevue WA

Assignee:

The Boeing Company - Seattle WA

International Classification:

G01S 1308

US Classification:

342128

Abstract:

A microwave transceiver using a reflection pumped mixer includes an electromagnetic signal generator, a subreflector, a reflector of electromagnetic signals from the subreflector, a mixer, circulator, and processing circuitry to relate electromagnetic signal frequency differences to the range of a target from the transceiver. Such frequency differences are detected by the mixer from the captured electromagnetic signals reflected distant targets and reflected electromagnetic signals from the subreflector.

International Classification:

H01Q 21280
G01S 13870

US Classification:

343720

Abstract:

A coaxial multiple-mode antenna system (10) is disclosed, including a coaxial input section (14) for coaxially collecting, for example, MMW and IR electromagnetic radiation. The IR radiation is focused to a point at the input section's focal plane, while the MMW beam has a relatively large width in this plane. An interface section (16) includes an IR section (18) and MMW section (20) that allow the two beams to be separately processed with a minimum of losses. In that regard, the MMW section includes a lens (42), having an incident surface, the center of which is positioned at the focal plane. An optical fiber (46) extends axially through the lens and has an incident end that is aligned with the incident surface of the lens. The lens quasi-optically transmits the MMW beam to a detection circuit (26), while the optical fiber transmits the IR beam to detection circuit (22). Because the optical fiber receives the IR beam before it is processed by the lens, IR losses are limited.

Appl. No.:

7/379817

Inventors:

Steven J. Peters - Renton WA

Assignee:

The Boeing Company - Seattle WA

International Classification:

H01Q 1302

US Classification:

343777

Abstract:

An electronically tunable phased array antenna element compensates for the variation of input impedance as the scan angle of the array changes. A microstrip feed is used which allows monolithic microwave integrated circuits to easily be incorporated in the radiating element housing. The element improves transmit or receive sensitivity. In addition, this electronic tuning will counteract detuning of the element caused by external influences such as electromagnetic field coupling from other nearby antennas.

Appl. No.:

7/265538

Inventors:

Steven J. Peters - Renton WA

Assignee:

The Boeing Company - Seattle WA

International Classification:

H01P 116

US Classification:

333 21A

Abstract:

A nearly square waveguide below cutoff has a microstrip substrate disposed diagonally therein. A first shunt capacitance is provided by either a conductor formed on the microstrip substrate or a conductor disposed in the waveguide perpendicular to the microstrip substrate. A dielectric window is disposed in the end to provide a shunt capacitance at the opposite end of the waveguide.
