| 5606414 | Interferometric ship's heading reference system Two Sagnac interferometers are mounted on board a ship with their axes in a horizontal plane. The axis of one interferometer is aligned in a fore-aft direction whereas the axis of the other interferometer is aligned athwartship. The output signals of the ... | 02/25/1997 |
| 5600285 | Monolithic stripline crossover coupler having a pyramidal grounding structure A coupler for crossing striplines which would otherwise intersect in a region of the substrate includes an electrically conducting housing through which transmission lines are passed that couple ends of the crossing striplines, formed by removing the cros... | 02/04/1997 |
| 5565879 | High scan rate low sidelobe circular scanning antenna An antenna for inertialess scanning a beam through 360 degrees or any desired sector thereof. A reflector, in the shape of a truncated cone that is tangential to an imaginary sphere in the central plane of the cone, is positioned above a feed array locate... | 10/15/1996 |
| 5561397 | Solid state amplifier for microwave transmitter A solid state amplifier for a microwave transmitter includes a power divider wherein a signal to be amplified is divided into signals of equal signal levels. The equal level signals are respectively coupled to a plurality of amplifiers wherefrom the ampli... | 10/01/1996 |
| 5502454 | Electrical conducting sheel structure for coaxial collinear array antenna A shell structure for a collinear coaxial element array antenna is made of electrical conducting material and includes first and second circular sections separated by a web. The first circular section has an inner diameter that is slightly larger than the... | 03/26/1996 |
| 5130712 | Microburst precursor detector utilizing microwave radar A microburst precursor detector utilizes a multiplicity of radar beams and samples radar returns, in each beam, from meterological radar signal reflectors and processes the signal returns in a statistical manner to determine average radar reflectivity and... | 07/14/1992 |
| 5028933 | Radial waveguide channel electronic scan antenna A limited scan antenna wherein radiating element and phase requirements are reduced by positioning the radiating elements to radiate through a radial waveguide. The longer wavelength in the radial waveguide relative to the free space wavelength permits a ... | 07/02/1991 |
| 5021793 | Phased array antenna method and system for adaptively positioning nulls A system for adaptively positioning nulls in the pattern of an antenna utilizing an auxiliary antenna in conjunction with a correlation receiver to determine the gain in amplitude and phase of the antenna pattern at the location of the interfering source.... | 06/04/1991 |
