An imaging system based on transmission and reflection modes in the terahertz region has been developed by using a backward-wave oscillator (BWO) as its source, a Golay-Cell as the detector, and an oscilloscope as a data acquisition unit.
Thanks to spatial power combining, these solid state power amplifiers (SSPAs) do not limit the amount of power that could be provided by an individual solid-state transistor—a problem that is often encountered when SSPAs are used in broadcast satellite-uplink terminals.
A test by the Missile Defense Agency demonstrated the interoperability of three regional missile defense systems: the Aegis Ballistic Missile Defense System, Patriot Advanced Capability-3 (PAC-3) Missile, and Terminal High-Altitude Area Defense (THAAD) weapon system.
With a single multi standard radio (MSR) base station unit now able to transmit GSM, WCDMA, and LTE multiple carriers simultaneously, the accurate and efficient testing of those MSR base station transmitter devices has become critical to their success.
Researchers have an opportunity to develop software according to the STRS architecture for radios for a new, flexible testbed on the International Space Station while reconfiguring how the radios communicate on-orbit.
