Research Interests and Activities

Range Characterization/Certification

I am interested in ways of better modeling and understanding the errors associated with measurement range characterization and certification. A large amount of work has gone on in this area for improving the measurements made on RCS ranges. I am also interested in extending these efforts into IR ranges, for better range characterization and measurements. For a brief overview of some of these efforts, look at the presentations below.

"ANSI/NCSL Z-540 in the IR Measurement Community," presented at the 2002 Conference on Characterization and Radiometric Calibration for Remote Sensing, April 29-May 2, 2002, Utah State University, Logan, UT.

"Certification: Assisting the IR Measurement Community," presented at the 6th Annual RCS Certification Conference, July 9-11, 2002 at NIST in Boulder, Colorado, USA.

For information concerning past and future RCS Certification Conferences, contact Roger W. Davis via email at or by phone at 301-863-0443.
 

Electromagnetic Compatibility

I am also interested in ways to minimize EMI/RFI in wireless and medical instrumentation systems. We are also investigating ways to more accurately model transmission systems, such as coaxial cables, to better predict interference effects, and the effects of cable defects on signal integrity.

NOTE: The 2002 IEEE International Symposium on EMC is being held August 19-23, 2002 in Minneapolis/St. Paul, Minnesota, USA. For information about this conference, go to: http://www.2002-ieee-emc.org/.

Microwave Engineering / Radar / Remote Sensing

My students and I are currently working on ways to accurately model entire radar systems in software. Initially, we are trying to emulate the Lab-Volt 8095 Training System. We chose this system because it can be operated in many modes, including CW, FW-CW, pulsed, digital, PPI, MTD, and due to the fact that it is modeled after the ASR-9 (MK 9 air surveillance radar system) which is used in many military and civilian airports. We are trying to emulate this system, using a combination of MATLAB and Labview to give ourselves a tool to evaluate the performance of radar systems, as well as examine different approaches to the processing of radar data for remote sensing and data fusion.

For additional information on the Lab-Volt 8095, see their web site at www.labvolt.com, select Training Systems and look under telecommunications.

Antenna Measurement Techniques

Finally, I am always looking for better ways to measure important parameters associated with antennas. We have an NSI Near-Field Scanner (Model 200V-3x3 Vertical Planar Scanner with Cylindrical Option) that we are incorporating into our research and eduacation activities. More to follow on this activity.

For additional information on the NSI Near-Field Antenna Scanners, see their web site at www.nearfield.com, and for more information about antenna measurements in general, visit the Antenna Measurement Techniques Association web site at www.amta.org.

I am always interested in discussing activities in these and related areas. If you have questions concerning our activities here, feel free to contact me at .
