The complexity of aerospace and defense software has grown manyfold. For example, the U.S. Air Force F-22 Raptor jet fighter, consists of about 1.7 million lines of software code, while the F-35 joint strike fighter has about 5.7 million lines…
Free-space optical communication (FSO) is an optical communication technology that uses light propagating in free space to wirelessly transmit data for telecommunications or computer networking. “Free space” means air, outer space, vacuum, or something similar. FSO operates on the Line-of-Sight…
One of the most common functions in all electronic circuitry is switching. Switching has a wide range of uses. Engineers in industries ranging from telecommunications to military/aerospace need high-performance RF/microwave switching as part of their test setups. An RF switch…
Michelson proposed an interferometric apparatus in 1890 following an earlier suggestion by Fizeau. The invention became the precursor of many important modern optic measurement techniques. The Michelson Interferometer, as it is called, is used to measure small optical path length…
Since fully autonomous UAS are still far off, the US Army has developed concept of Manned-unmanned teaming (MUM-T) for operation in A2/AD environments. Through MUM-T operations they expect to combine the strengths of manned and unmanned platform to increase situational…
US military is facing increasingly Anti-access /Area denial environment, a set of overlapping military capabilities and operations designed to slow the deployment of U.S. forces to a region, reduce the tempo of those forces once there, and deny the freedom…
The terahertz (THz) frequency band is a fascinating and relatively unexplored part of the larger electromagnetic spectrum (EMS). The terahertz frequency range, lying between electronics and optics (300 to 3000 gigahertz frequencies), can be disruptive force in sectors as diverse as…
The fiber optic sensors also called as optical fiber sensors use optical fiber or sensing element. These Sensors can measure a large variety of parameters, such as temperature, pressure, strain, refractive index, vibrations, displacements, bending, loading, and liquid level or…
In 2016, The Army’s chief information officer announced the release of the Army’s new, long-term, network strategy called “Shaping the Army Network (2025-2040).” The document discusses the projected operational environment and required capabilities to set the context for what the…
The need for better radar in World War II drove the development of radio frequency control, and its miniaturization in subsequent decades revolutionized a host of military and consumer applications. The generation of accurate signal frequencies from a single reference…
