Optoelectronic technology is a new technology formed by the combination of photon technology and electronic technology. Optoelectronics is the field of technology concerned with electronic device application to the sourcing, detection and control of light. Optoelectronics is described as “a device that responds to optical power, emits or modifies optical …

A hydrophone is an underwater listening device, just as a microphone is used to detect sound in the air. Hydrophone detects sounds in the water and converts the acoustic energy into electrical energy by detecting changes in pressure in the surrounding environment. Hydrophones listen to sounds in the sea, but …

In recent years organized crime in maritime regions has flourished, threatening both secure flow of goods from Exclusive Economic Zones (EEZ) and lives of participants in the marine operations. Security threats and humanitarian risks caused by trafficking (drugs, weapons, etc.), irregular transport of migrants, maritime terrorism or even piracy are …

The military uses the electromagnetic spectrum — essential, yet invisible — to detect, deceive and disrupt the enemy while protecting friendly forces. As enemies become more capable and threats more complex, controlling the spectrum is increasingly critical. However, today’s electromagnetic (EM) spectrum is a scarce resource that is becoming increasingly …

DoD is exploring opportunities to incorporate autonomy, AI, and human-machine teaming into its weapons and operations. Whether as data-mining tools for intelligence analysts, decision aids for planners, or enablers for autonomous vehicle operations, these systems have the potential to provide more accuracy, speed, and agility than traditional tools. Yet operational …

Radio frequency (RF) technologies have limitations that cannot fulfill specific requirements. For instance, underground and underwater are challenging environments due to the absorption of high frequency electromagnetic (EM) waves in dense media. For hypersonic communications, Very Low Frequencies (VLF) band signals have large EM wavelengths that can penetrate the plasma …
