International Classification:

G01R 1/20
G01R 31/308

US Classification:

324144, 32475012

Abstract:

Systems and methods to stir an electromagnetic (EM) field of an EM reverberation chamber are disclosed. A particular system includes an EM reverberation chamber. The system also includes a transmit antenna and a receive antenna operable to generate an EM field within the EM reverberation chamber. The system further includes a variable charged particle source to stir the EM field by varying introduction of charged particles into the EM field.

Appl. No.:

13/431582

Inventors:

Jason Andrew Koehn - Enumclaw WA, US
James K. Whitley - Gig Harbor WA, US
Shawn Paul Snell - Monroe WA, US

Assignee:

THE BOEING COMPANY - Chicago IL

International Classification:

G06F 19/00
G01F 1/00

US Classification:

702 45

Abstract:

A velocity mapping system comprising a sensor system and an airflow mapper. The sensor system is configured to generate data about a velocity of airflow for a location in a duct system. The airflow mapper is configured to receive the data from the sensor system and generate a profile of the velocity of the airflow at the location in the duct system.
