- Description
- TECHNOLOGY/BUSINESS OPPORTUNITY Technique for Detection and Directionality Determination of Electromagnetic Sources Opportunity: Lawrence Livermore National Laboratory (LLNL), operated by the University of California under contract with the U.S. Department of Energy (DOE), is offering the opportunity to partner with LLNL to develop hardware and software related to the detection and directionality determination of electromagnetic (EM) signal sources. This new, potentially portable technology is intended to identify and locate low-frequency electromagnetic noise sources in order to take off-line or quickly isolate and repair the interfering electrical/electronic equipment operating in buildings, factories and large commercial facilities. The technology will also have application relating to locating general EM signal sources having frequencies falling within the operational bandwidth of the receiver. Background: At present, sources of interfering electrical noise in a facility must be detected using a time-consuming trial-and-error approach. It is expensive because resolving such problems is often performed by independent electrical noise consultants contracted on a daily basis. Current techniques for detecting and determining the direction of EM signal sources generally involve the use of large and unwieldy directional antennas having diameters of many meters or the use of antenna arrays. In practice, the large size of a directional antenna renders impractical obtaining the source direction from very low-frequency signals (hertz to kilohertz range) such as the electrical noise harmonics that commonly emanate from the power supplies of electronic systems. In addition, common antennas and receivers for detecting EM signals are usually designed only to capture the electric-field component of the signal. Since electromagnetic waves are characterized by both electric and magnetic field potentially significant information is lost. Description: The LLNL approach uses both the electric and magnetic components of an electromagnetic wave, which provides information about the direction of wave emanation as well as the flux of energy in the wave. Advantages: ?X Directionality can be readily determined ?X Potentially highly portable ?X Diagnostic tool rather than trial and error method ?X Locate lower frequency (e.g., power-line frequency and associated harmonics) electrical interference noise sources in complex electrical/electronic environments. ?X Locate non-noise sources that have frequency components falling within the operational bandwidth of the receiver. Potential Applications: Electrical noise detection and elimination as well as non-noise signal location has commercial, law enforcement and military applications. Specifically, the features and benefits to the applications are listed below. Feature Benefit Measure both the electric and magnetic fields of an electromagnetic wave ? Antenna size comparable to wavelength of signal being acquired is not required ? Makes possible low frequency noise directionality applications and portability Separate and identify different frequency sources through signal analysis ? Directions of slightly different signals that even overlap in frequency can be isolated from each other Antennas are omni-directional ? All signals in a given frequency range are captured ? Intermittent noise or signals of interest will not be missed as for directional antennas pointed in the wrong direction ? Moving sources can be tracked without re-orienting receiver. Directionality obtained entirely through analysis of acquired signal and not by a hands-on re-orienting of antenna during signal acquisition ? Signal direction can be obtained either in real time or by postprocessing of saved digital signal data. ? Data can be acquired passively and in remote environments without human involvement Development Status: Initial field testing has identified noise signals from a power generator and load. providing directional information about the noise source. These tests have made apparent the advantages of measuring both the electric and magnetic fields of a signal. Further development is needed to scale down the electric- and magnetic-field antennas, the receiver and the processing hardware to a convenient level of portability (e.g., handheld). The analysis technique has been developed through subsequent detailed computer simulations of noise and signal sources, but is still in development and can benefit from signal processing and optimization development. LLNL is seeking industry partners with a demonstrated ability to bring such inventions to the market. Moving critical technology beyond the Laboratory to the commercial world helps our licensees gain a competitive edge in the marketplace. All licensing activities are conducted under policies relating to the strict nondisclosure of company proprietary information.
