Modern electromagnetic interference (EMI) receivers and spectrum analyzers used for compliance and precompliance testing employ digital intermediate-frequency (digital IF) processing technology for signal...

In order to transmit communications through Earth’s atmosphere, satellites and space vehicles need radio equipment that can operate at higher frequencies than on Earth. These higher frequencies, until...

NASA’s Langley Research Center hoisted a Cessna 172 aircraft 100 feet into the air by cables and released it. The plane plummeted onto a slab of dirt in a violent but controlled experiment that...

The need for a high-bandwidth communication link to carry multiple video channels from a mobile robot (unmanned ground vehicle, or UGV) back to a control station requires using high-frequency RF...

One of the methods for radar testing is the simulation of an environment where there are dynamic or static objects that are scanned by the radar under test. In particular,...

Meeting the performance needs of the next generation of radar systems that will be deployed by the military is spurring the development of more efficient and sensitive...

When U.S pilots encounter enemy air defenses, onboard electronic warfare (EW) systems protect them by interfering with incoming radar signals — a technique...
