Real-Time Error-Suppression Method And Apparatus Therefor

US Patent:
6606583, Aug 12, 2003
Filed:
Sep 21, 1999
Appl. No.:
09/400220
Inventors:
Ben K. Sternberg - Tucson AZ, 85704
Steven L. Dvorak - Tucson AZ, 85749
International Classification:
H04B 1500
US Classification:
702191, 702106, 702109, 324616
Abstract:
A thorough error suppression signal measurement system (20) having a transmitter (300) for propagating a transmission signal to a first probe 100, through a device under test (26), and into a second probe (200), and for propagating reference signals to the probes (100,200). The probes (100,200) extract normalization signals from the reference signals, exchange specific ones of the normalization signals, and combine the normalization signals with data signals derived from the transmission signal to form receiver signals. The probes (100,200) propagate the receiver signals to a receiver (400), where the signals are gain-ranged, digitized, normalized, and compensated for phase-noise.

Abstract:
An error-suppression signal measurement system and method therefor is provided. The system transmits a test signal from a first probe, through a device under test, and into a second probe. The probes extract normalization signals from reference signals therein, exchange specific ones of the normalization signals, and combine the normalization signals with data signals derived from the test signal to form receiver signals. The probes propagate the receiver signals to a receiver, where the signals are gain-ranged, digitized, normalized, and compensated for phase-noise.

Vector Signal Measuring System, Featuring Wide Bandwidth, Large Dynamic Range, And High Accuracy

US Patent:
8155904, Apr 10, 2012
Filed:
Sep 22, 2008
Appl. No.:
12/235217
Inventors:
Steven L. Dvorak - Tucson AZ, US
Ben K. Sternberg - Tucson AZ, US
International Classification:
G01R 13/00
US Classification:
702 66
Abstract:
A new measurement system, with two receiver channels per measurement port, has been developed that provides absolute magnitude and absolute phase relationship measurements over wide bandwidths. Gain ranging is used at RF to provide optimum noise performance and a swept YIG preselector filter is used to avoid spurious signals. A new absolute vector error correction method is used to calibrate the measurement system in order to allow for absolute vector measurements, and it also removes the time-varying responses caused by the swept YIG preselector filters. A quasi-reciprocal mixer with a characterized non-reciprocal ratio is used to provide the absolute calibration standard. The two receiver channels can be adapted to a wide variety of applications, including wide bandwidth vector signal analyzer measurements, mixer measurements, and harmonic measurements. The two-channels can also be used as an absolute calibrated transmitter/reflectometer.

Differential Target Antenna Coupling (Dtac)

US Patent:
2011009, Apr 28, 2011
Filed:
Oct 26, 2010
Appl. No.:
12/912511
Inventors:
Steven L. Dvorak - Tucson AZ, US
Ben K. Sternberg - Tucson AZ, US
International Classification:
G01R 23/02
US Classification:
324 7639
Abstract:
Sub-surface detection systems include a transmitter antenna and a receiver antenna that is coupled to a receiver circuit. The receiver antenna is rotated to three different orientations, and a reference null field direction is determined. Based on variations in the null field direction at other frequencies or variations in a magnitude of a field component in the reference null field direction, the presence, location, depth, size, and electrical properties of a target can be determined.

Differential Target Antenna Coupling (Dtac) Data Corrections

US Patent:
2020011, Apr 9, 2020
Filed:
Dec 3, 2019
Appl. No.:
16/701956
Inventors:
- Tucson AZ, US
Ben K. Sternberg - Tucson AZ, US
International Classification:
G01V 3/10
G01R 23/02
G01V 3/38
G01V 3/12
Abstract:
The present invention features a unique system of interdependent methods to greatly improve data acquired via the Differential Target Antenna Coupling (“DTAC”) method, which transmits electromagnetic (“EM”) fields and measures the primary EM field and the secondary EM fields generated in subsurface targets. These new data correction techniques provide improvements, in orders of magnitude, to the measured DTAC response accuracy. This improvement allows for greater depth of investigation, improved target location, and enhanced target characteristics.
