Method And Apparatus For Radio Location
View pageUS Patent:
6573865, Jun 3, 2003
Filed:
Feb 23, 1998
Appl. No.:
09/028063
Inventors:
Elie J. Baghdady - Weston MA, 02193
International Classification:
G01S 504
US Classification:
342437, 342442, 342446, 375148
Abstract:
This disclosure relates to multi-element antenna clusters or arrays for the reception and transmission of radio waves for direction-finding, navigation aid and emitter and/or receiver location purposes. In particular, it relates to arrangements of multiple antennas whereby the direction of propagation (arrival or departure) of a wavefront is determined from a combination of the amplitudes of phasor (or total individual antenna output) differences between pairs of antennas, said arrangements being along certain geometrical patterns, such as a circle, an ellipse, a polygon, an open straight line, etc. , with at least one longest dimension measuring more than one wavelength of the incident or departing wave. Although described in terms of electromagnetic waves and hence antennas as receiving sensors or radiators, this invention in reality applies to any other form of propagating waveborne energy, such as acoustic, ultrasonic, seismic, etc.
Method And Apparatus For Signal Modulation And Detection
View pageUS Patent:
52648575, Nov 23, 1993
Filed:
Sep 30, 1991
Appl. No.:
7/767886
Inventors:
Elie J. Baghdady - Weston MA
International Classification:
G01S 504
H04B 110
H04B 110
US Classification:
342433
Abstract:
The disclosure relates to methods and apparatus for separating radio signals arriving from different directions and for multiplexing signals intended for receivers dispersed in different directions. The methods and apparatus employ a plurality of antennas with spacing and individual feedline characteristics designed so that a modulation is imparted to each of a plurality of incident signals, for receiving antennas, and radiated signals for transmitting antennas, the modulation level of each signal being determined by the direction of propagation of the signal and by the spacing between antenna pairs. Accordingly, the orientation of lines connecting pairs of antennas as well as the spacing between antennas are set to inhibit the modulation in a particular direction, or to strip a particular modulation off a signal incident from a selected direction.
Method And Apparatus For Signal Detection, Separation And Suppression
View pageUS Patent:
43285910, May 4, 1982
Filed:
Apr 23, 1979
Appl. No.:
6/032405
Inventors:
Elie J. Baghdady - Weston MA
International Classification:
H04B 110
US Classification:
455303
Abstract:
The disclosure relates to methods and devices for separating and suppressing an interfering or jamming signal which is the strongest of a plurality of linearly combined signals and which carries modulation including at least amplitude modulation. The methods and devices collapse the frequency spectrum of the strongest signal to substantially a single frequency and filter out that single frequency.
Signal Modulation Methods And Apparatus
View pageUS Patent:
54345774, Jul 18, 1995
Filed:
Nov 17, 1989
Appl. No.:
7/437898
Inventors:
Elie J. Baghdady - Weston MA
International Classification:
G01S 316
US Classification:
342380
Abstract:
The disclosure relates to methods and apparatus for facilitating the accurate measurement of Doppler frequency shift induced on a one-way-propagated signal wave either by deliberate on-platform controlled actual or simulated motion of a receiving antenna means, or by relative motion between transmitting and receiving platforms, or by both. The methods and apparatus of this invention are directed to the suppression of identifiable components of a composite modulation process on a sinusoidal carrier, for the purpose of retaining, for separate detection, measurement or transmission, the result of any of the aforementioned frequency-shift inducing processes.
Tracking And Position Determination System
View pageUS Patent:
40608093, Nov 29, 1977
Filed:
Apr 9, 1975
Appl. No.:
5/566195
Inventors:
Elie J. Baghdady - Weston MA
International Classification:
G01S 140
G01S 354
G01S 504
G08G 500
G01S 354
G01S 504
G08G 500
US Classification:
343112R
Abstract:
A method and apparatus for tracking and position determination includes generating carrier waves in transmitters; radiating said carrier waves; receiving said radiated carrier waves; imparting or simulating a motion, or motions, to radiators, reflectors or/and receiving antennas, within the locality of each, in such a way as to induce direction-dependent frequency modulation in each signal delivered to the receiving detectors; detecting said modulation on each received signal; and using measured parameters of said detected modulation to track the location of one or more of the said transmitters, reflectors or/and receivers and determine the corresponding position coordinates thereof. The actual or simulated motion of the radiators reflectors or antennas may have a uniform velocity along at least two straight, non-parallel lines.
Radar Method And Apparatus
View pageUS Patent:
42031133, May 13, 1980
Filed:
Aug 4, 1978
Appl. No.:
5/931000
Inventors:
Elie J. Baghdady - Weston MA
International Classification:
G01S 924
US Classification:
343 14
Abstract:
The disclosure relates to radar methods and systems for directionally selective detection of objects and determination of the distances to the objects. A rectangular-wave frequency-shifted radar signal is employed. This radar signal may be generated by inducing a directionally dependent Doppler shift which permits directionally selective detection. Higher and lower frequency portions of the returned radar signal are separately frequency converted and phase compared to determine range. In a preferred embodiment, a collision avoidance system for automobiles is provided.
Interference Rejection Technique
View pageUS Patent:
40889556, May 9, 1978
Filed:
Apr 7, 1975
Appl. No.:
5/565591
Inventors:
Elie J. Baghdady - Weston MA
International Classification:
H04B 702
US Classification:
325 56
Abstract:
This invention relates to interference suppression or reduction means in receiving systems, and more particularly to apparatus for suppressing interference in receiving equipment by locally inducing a sufficiently large frequency difference between a desired signal and an undesired signal arriving from a different direction at the receiving site.
Method And Apparatus For Diversity Reception
View pageUS Patent:
53393341, Aug 16, 1994
Filed:
Dec 20, 1991
Appl. No.:
7/811292
Inventors:
Elie J. Baghdady - Weston MA
International Classification:
H04B 710
H04L 102
H04L 102
US Classification:
375100
Abstract:
The disclosure relates to methods and apparatus for combining a multiplicity of diversely received replicas of a signal originating in the same remote transmitter. The disclosed methods and apparatus apply, in particular, to digitally modulated sinusoidal prime-carriers or subcarriers, and base the final decision about which of the code alphabet symbols is present in each bit-symbol time slot on either: a) the maximum value of a decision index for each code alphabet letter indicated in/for the same bit time-slot by parallel bit-by-bit detection of the diverse replicas of the signal, the decision index being defined as a function only of the pre-video (IF carrier or subcarrier) signal-to-noise power ratios of the various signal replicas that yield the same code alphabet letter; or on b) bit-by-bit detection of the maximal ratio combination of the video (or pre-bit-detection) bit-stream waveforms out of the prime-carrier or subcarrier exponent (i. e. , phase or frequency) demodulators.
