“We have an outstanding electromagnetic interference team here at the Benefield Anechoic Facility … they’re highly competent at what they do and they’re continuously working towards improving the unique capability of the facility to help defend this nation,” he noted.
Northrop Grumman senior electromagnetic interference engineer, Dick Hohol, is supporting the test with engineers Monty Hall and Chuck Wilkerson from the Unmanned Systems Operation in Rancho Bernardo, Calif.
The team also received technical support from Rocky Furton of the Northrop Grumman Antelope Valley Manufacturing Facility.
“The Benefield Anechoic Facility enables us to perform highly accurate and repeatable measurements of antenna to antenna RF coupling in an environment representative of flight,” Hohol said.
“Without a facility like the Benefield Anechoic Facility, it would be necessary to conduct extensive flight testing on the Global Hawk to identify electromagnetic interference issues and even further testing to verify the performance of any mitigation treatments,” he explained.
This test of the Global Hawk unmanned aerial vehicle is one of a series of evaluations of this major intelligence gathering weapon system at the facility.
Tests, such as this one on the Global Hawk, enhance overall warfighter capability by minimizing the electromagnetic interference effects on the vehicle and help maximize the reliability and accuracy of data provided to combatant commanders in the field by the Advanced Signals Intelligence Payload SIGINT system so they’re able to make better decisions in real time.
