Gary Kentosh - Bell Canyon CA
Assignee:
ITT Manufacturing Enterprises, Inc. - Wilmington DE
International Classification:
G01S 1393
US Classification:
342 34
Abstract:
A radar system which time shares the use of a common radar head to perform functions associated with Air Surveillance Radar (ASR) and Precision Approach Radar (PAR) systems, i. e. , for respectively displaying information to an air traffic controller useful for tracking an aircraft's approach to an airport and then guiding said aircraft along a preferred glideslope approach to a runway. In accordance with a significant feature of a preferred embodiment, a common radar head is comprised of an azimuth antenna capable of using radar beams to scan, e. g. , electronically, a subsidiary scan arc, i. e. , less than. +-. 90. degree. , mounted on a rotational scan apparatus that directs said radar beams within a principal scan arc, a full circle (360. degree. ), by continuously rotating, e. g. , mechanically, said azimuth antenna at an essentially constant rate.

Low Level Controllable Radio Frequency Phase Shifter

View page
US Patent:
41617053, Jul 17, 1979
Filed:
Dec 19, 1977
Appl. No.:
5/861524
Inventors:
Jeffrey T. Nemit - Canoga Park CA
Ronald I. Wolfson - Northridge CA
Assignee:
International Telephone and Telegraph Corporation - New York NY
International Classification:
H03H 720
H03H 722
H01P 118
US Classification:
333156
Abstract:
The invention involves in-phase power splitting from an input into separate pairs of paralleled input variable circuits which may be linear amplifiers or linear controlled attenuators. The outputs of these circuits feed the input branches of a pair of 180. degree. hybrid circuits, the outputs of those hybrids providing the inputs of a 3 db quadrature coupler. An output of this coupler then provides the overall output which is shifted in phase with respect to the original input as a function of the gain control signal applied differentially between the variable circuits of the aforementioned pairs as the cosine of the desired phase angle in respect to the first pair of circuits and in accordance with the sine of the desired phase angle at the control terminals of the second pair of circuits.

Large Scale Low-Loss Combiner And Divider

View page
US Patent:
42635683, Apr 21, 1981
Filed:
Mar 12, 1979
Appl. No.:
6/019481
Inventors:
Jeffrey T. Nemit - Canoga Park CA
Assignee:
International Telephone and Telegraph Corporation - New York NY
International Classification:
H01P 512
US Classification:
333127
Abstract:
A radio frequency power divider/combiner having a pair of conductive plates between which the dominant E-type mode is produced by symmetrical excitation at a central point preferably by means of a coaxial line having its outer conductor attached to the first of these plates, and its inner (center) conductor passing freely therethrough and attaching to the second of these parallel plates in an impedance matching flareout. A plurality of uniformly distributed collectors each in the form of a loop feeding the coaxial branch port provides for low loss. The entire assembly is in the form of a thick disc with radially extended branch ports about its perimeter and a common excitation feed extending normally from the surface of the first plate. Resistors are provided between adjacent portions of the end-on loops for the suppression of circumferential current components corresponding to undesired modes.

Electronic Scanned Cylindrical-Array Antenna Using Network Approach For Reduced System Complexity

View page
US Patent:
39640663, Jun 15, 1976
Filed:
Jan 2, 1975
Appl. No.:
5/538193
Inventors:
Jeffrey T. Nemit - Canoga Park CA
Assignee:
International Telephone and Telegraph Corporation - New York NY
International Classification:
H04B 700
US Classification:
343100SA
Abstract:
An electronic scan system with excitation arrangement for producing a directive radiation pattern from a circular or cylindrical array at a predetermined pointing angle. The circular or cylindrical array provides random beam pointing. An RF input-output port feeds an equal amplitude distribution network providing as many outputs as there are elements of the array employed at any given time. An equal number of phase shifters is included, and gross beam positioning is effected through selection of the contiguous element group to be excited by means of RF switching. The phase shifters may then be controlled to provide the specific beam pointing or scan desired within the selected sector. The antenna elements of the array are fed through a passive interconnecting matrix responsive thereto, said matrix providing inherent amplitude taper across the effective aperture. The passive interconnecting matrix replaces the more complicated and expensive "ordering" matrix employed in prior art systems of the same general type.

Multibeam Slot Array

View page
US Patent:
41647424, Aug 14, 1979
Filed:
Dec 29, 1977
Appl. No.:
5/865614
Inventors:
Jeffrey T. Nemit - Canoga Park CA
Assignee:
International Telephone and Telegraph Corporation - New York NY
International Classification:
H01Q 1310
US Classification:
343768
Abstract:
A slotted-waveguide linear array in which a pattern of slots in a narrow wall of a first waveguide forms the aperture of the array. A second waveguide runs parallel to the first guide, the other narrow wall of the first waveguide being a common wall with the second waveguide. The pattern of coupling holes through this common wall couples energy between the waveguides. A feed arrangement, preferably including a 180. degree. hybrid, has two of its ports connected one each to the first and second waveguides, the difference port, when driven, providing 180. degree. phase feed of the two waveguides so that the presence of the second waveguide is substantially nil. Thus, a single beam is formed as if the second waveguide were not present. The feed also provides for excitation of the waveguides through a mutual hybrid in-phase relationship when the sum port of the hybrid is driven, in which case the beam is angularly separated from the original beam.

Network-Fed Phased Array Antenna System With Intrinsic Rf Phase Shift Capability

View page
US Patent:
39697290, Jul 13, 1976
Filed:
Mar 17, 1975
Appl. No.:
5/558705
Inventors:
Jeffrey T. Nemit - Canoga Park CA
Assignee:
International Telephone and Telegraph Corporation - New York NY
International Classification:
H01Q 326
US Classification:
343756
Abstract:
An integral element/phase shifter for use in a phase scanned array. A non-resonant waveguide or stripline type transmission line, series force feeds the elements of an array. In the embodiments shown, four RF diodes are arranged in connection within the slots of a symmetrical slot pattern in the outer conductive wall of the transmission line to vary the coupling therefrom through the slots to the aperture of each individual antenna element. Each diode thus controls the contribution of energy from each of the slots (at a corresponding phase) to the individual element aperture and therefore determines the net phase of the said aperture. Three species of the invention are shown, the first and second involving RF diodes in the slots of waveguide broad and narrow walls respectively, and the third having slots through the shield plane of a stripline. The invention facilitates array phase scanning without the need for separate, and relatively more expensive, discrete phase shifters for each antenna element.

Three-Way, Equal-Phase Combiner/Divider Network Adapted For External Isolation Resistors

Inventors:
Jeffrey T. Nemit - Canoga Park CA
George A. Hockham - Valencia CA
Ronald I. Wolfson - Northridge CA
Assignee:
International Telephone and Telegraph Corporation - New York NY
International Classification:
H01Q 1310
US Classification:
343771
Abstract:
An integrated planar antenna array comprising at least two separate interleaved arrays separately controllable and responding to separate frequency bands. Both arrays operate with substantially the same phase center and substantially within the same effective aperture. The first array or subarray comprises spaced linear, slotted-waveguide arrays and the second subarray includes a meander line occupying the space between each of the waveguides of the first array. Scan systems are shown for independent operation of the two arrays. An alternative for the second subarray is shown in the form of slotted, square-coaxial, linear arrays in the spaces between the waveguides of the first subarray.
