Ruy L. Brandao - Fort Lauderdale FL
Ruy C. P. Brandao - Redmond WA
Assignee:
AlliedSignal - Morristown NJ
International Classification:
G01S 1376
G01S 1387
US Classification:
342 30

Antenna Stabilization Error Correction System For Radar

View page
US Patent:
54851564, Jan 16, 1996
Filed:
Sep 21, 1994
Appl. No.:
8/310117
Inventors:
Arezki Manseur - Boca Raton FL
William C. Weist - Boca Raton FL
Ruy L. Brandao - Fort Lauderdale FL
Phillip R. Hermann - Coral Springs FL
Assignee:
AlliedSignal Inc. - Morris Township, Morris County NJ
International Classification:
G01S 1366
US Classification:
342 77
Abstract:
A radar utilizes an antenna stabilization error correction system to automatically estimate and correct attitude sensor errors in pitch, roll and elevation. The radar system includes an antenna, an antenna positioner, a transmitter receiver, a signal processor, an antenna controller and stabilization processor and the antenna stabilization error correction system. As part of the normal signal processor sub function, ground clutter signals are extracted from the received signals. These signals are the primary input to the antenna stabilization error correction system. Other inputs are received from the signal processor, antenna controller and stabilization processor and an external aircraft radio altimeter. The antenna stabilization error correction system processes the signals and estimates pitch, roll and elevation errors which are passed back to the antenna controller and stabilization processor.

Radar Display System

US Patent:
40178536, Apr 12, 1977
Filed:
Jul 11, 1975
Appl. No.:
5/595967
Inventors:
Ruy L. Brandao - Fort Lauderdale FL
Robert A. Taylor - Fort Lauderdale FL
Assignee:
The Bendix Corporation - Southfield MI
International Classification:
G01S 902
G11C 800
US Classification:
343 5DP
Abstract:
In a radar display system wherein radar return signals are received at a first rate and displayed at a second, usually higher rate, each radar return signal is digitized and used to update a main memory comprised of a random access memory so that the main memory contains information related to a plurality of radar return signals arranged therein in a logical order. The main memory information is continuously clocked out for display by an address counter which counts through two complete cycles in a first stage before incrementing a second stage so that the stored information related to each radar return signal is read out for display twice consecutively before the stored information related to the next radar return signal is read out for display.

Transponder Having Directional Antennas

View page
US Patent:
63137836, Nov 6, 2001
Filed:
Aug 6, 1999
Appl. No.:
9/369958
Inventors:
Daryal Kuntman - Bellevue WA
Ruy L. Brandao - Fort Lauderdale FL
Ruy C. P. Brandao - Redmond WA
Assignee:
Honeywell International, Inc. - Morristown NJ
International Classification:
G01S 1374
G01S 1393
US Classification:
342 32
Abstract:
A method and apparatus for transmitting a directional reply signals in response to Air Traffic Control Radar Beacon System and Mode Select signals interrogation signals. Two directional antennas independently acquire an interrogation signal and are connected by means of a configurable switch to a transponder. The antennas may include multiple directional antenna elements.

Data Display System Having A Multilevel Video Storage Device

View page
US Patent:
39640647, Jun 15, 1976
Filed:
Nov 21, 1973
Appl. No.:
5/418154
Inventors:
Ruy L. Brandao - Fort Lauderdale FL
Robert A. Taylor - Fort Lauderdale FL
The Bendix Corporation - Southfield MI
International Classification:
G01S 704
US Classification:
343 5SC
Abstract:
A radar return signal is analyzed by amplitude comparators so as to classify the radar return signal with respect to 2. sup. n -1 threshold levels to thus produce n parallel bits for each classification defining the instantaneous amplitude of the radar return signal. The bits in a given significant bit position (most significant, least significant, etc. ) comprise a word which moves through the video storage device serially with respect to bits in the same significant bit position and in parallel with respect to bits in the word comprised of different significance bits. Input buffers in the form of n storage registers are provided, each storage register being associated with a particular bit significance. The bits are entered into their associated storage register at a rate dependent upon the desired radar range. The bits are optionally integrated on a bit-by-bit basis and then entered into a main memory having n circulating storage registers arranged in parallel.

Neutralization Network For Multielement Antenna

View page
US Patent:
51913402, Mar 2, 1993
Filed:
Aug 16, 1991
Appl. No.:
7/746384
Inventors:
Ruy L. Brandao - Fort Lauderdale FL
Anthony Parker - Boca Raton FL
Randall C. Spires - Boca Raton FL
Assignee:
Allied-Signal Inc. - Morris Township, Morris County NJ
International Classification:
H01Q 322
H01Q 324
H01Q 326
US Classification:
342373
Abstract:
A distributed network that compensates for the effects of interelement coupling in a multielement antenna array is inserted between the output of an antenna array and the inputs of a receiver system. Within the distributed network are a plurality of couplers interconnected by transmission lines serving as phase shifters. The coupling factors of the various couplers and the lengths of the transmission lines are selected so as to apply voltage components of specific amplitudes and phase to the antenna ports. The values of the amplitudes and phases of these voltage components are such as to neutralize the components of the voltages at the output of the antenna array which are caused by the spatial couplings between the elements of the antenna array.

Methods And Systems Of Determining Bearing When Ads-B Data Is Unavailable

US Patent:
20100250138, Sep 30, 2010
Filed:
Jun 7, 2010
Appl. No.:
12/795511
Inventors:
Ruy L. Brandao - Ft. Lauderdale FL, US
Christine M. Haissig - Chanhassen MN, US
John Weed - Mill Creek WA, US
Eric A. Euteneuer - Minneapolis MN, US
Assignee:
HONEYWELL INTERNATIONAL INC. - Morristown NJ
International Classification:
G01S 13/93
G01S 13/75
G08G 1/16
US Classification:
701301
Abstract:
System, method and computer program product for determining bearing using ADS-B and TCAS standard reply bearing estimates are disclosed. In one embodiment, a method for determining bearing based upon ADS-B signals includes receiving ADS-B signals and standard transponder reply signals. A first bearing estimate is based on the ADS-B signal. A second bearing estimate is based on the standard transponder reply signals. A database is developed according to the first and second bearing estimates via the ADS-B and standard transponder reply signals. In one embodiment, where ADS-B signals are unavailable, associated ADS-B signals associated with the standard transponder reply previously stored in the database are used to determine bearing.
