Wireless electronic systems have been relying on dish antennas to send and receive signals. These systems have been widely used where directivity is important and many of those systems work well at a relatively low cost after years of optimization. These dish antennas having a mechanical arm to rotate the …

The Global Positioning System (GPS), is a global navigation satellite system (GNSS) that provides location and time information in all weather conditions, anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. Each one transmits information about its position and …

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 of code to operate its onboard systems. Boeing’s new 787 …

UAVs have evolved into increasingly capable platforms deployed for a wide variety of applications. The capability to fight effectively in urban areas against widely dispersed forces, while minimizing collateral damage and achieving information superiority has enabled the UAVs to play a greater role in critical missions. The UAVs have become one …

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 awareness, allowing the armed forces to conduct operations that include …

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 from medical imaging, biological research, pharmaceutical monitoring, manufacturing and quality …

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 concentration of chemical species. Fiber optic sensors have become a …

UUVs—submersible unmanned vehicles—are divided into two categories: remotely operated underwater vehicles (ROVs) and autonomous underwater vehicles (AUVs). ROVs are controlled and powered by a person or crew on either land or neighboring craft via an umbilical or using remote control. The cables enable maneuverability of the ROV, allowing it to travel …
