Filed:

Sep 18, 2009

Appl. No.:

12/562134

Inventors:

Charles R. Crain - Colorado Springs CO, US
Phillip D. Lane - Colorado Springs CO, US
Kelly L. Rice - Colorado Springs CO, US
James A. Youngman - Woodland Park CO, US

Assignee:

L-3 Communications Corporation - New York NY

International Classification:

G01R 27/28
G01N 27/82

US Classification:

324627, 324240

Abstract:

An embodiment disclosed herein is directed to a method of monitoring an electromagnetic shield effectiveness including transmitting a first electromagnetic field toward a first surface of an electromagnetic shield, detecting a second electromagnetic field transmitted from a second surface of the electromagnetic shield, generating a first signal corresponding to the second electromagnetic field and determining whether a defect exists at the electromagnetic shield by comparing the first signal to a predetermined threshold.

International Classification:

G01R 27/28

US Classification:

324627

Abstract:

An embodiment disclosed herein is directed to an electromagnetic shielding defect monitoring system that includes a transmit system adapted to transmit a first electromagnetic field toward a first surface of an electromagnetically shielded enclosure, thereby generating a first current on the first surface, a stationary receive system adapted to detect a second electromagnetic field transmitted from a second surface of the electromagnetically shielded enclosure by a second current induced on the second surface by the first current and to generate a corresponding detected signal; control circuitry adapted to control operations of the transmit and receive systems; and analysis circuitry adapted to identify a location of a defect in the electromagnetically shielded enclosure based upon operations of the transmit and receive systems and based upon the detected signal.

International Classification:

G01R 29/08

Abstract:

The present invention is a remotely controlled, automated shielding effectiveness test system for hardening against the effects of high altitude electromagnetic pulses. The system monitors and reports the on-going effectiveness of an enclosure that shields electronic devices and communications systems from electromagnetic pulses. The system reports provide information to a user to determine whether corrective action is needed for the enclosure to ensure continued protection of the electronic devices and communications systems within the enclosure. The system comprises providing a high-altitude electromagnetic pulse (HEMP) enclosure enclosing at least an electronic device, and an electronic testing apparatus for testing effectiveness of HEMP shielding of the enclosure; and performing a shielding effectiveness test by the apparatus on the enclosure, comprising a first compression sub-test, a second environment sub-test, and a third final shielding effectiveness sub-test.
