Precision Guidance Kit turn artillery rounds into smart weapons that penetrate A2/AD environments and destroy threats even in GPS jammed environments

October 18, 2021 Electronics & EW, Weapons Comments Off on Precision Guidance Kit turn artillery rounds into smart weapons that penetrate A2/AD environments and destroy threats even in GPS jammed environments

Artillery ammunition is designed for use in guns, howitzers, and mortars. Size designations for artillery ammunition range from 37MM through 280MM. Artillery ammunition can be classified according to weapon system (gun, howitzer, mortar), filler composition (explosive or chemical), and military use (practice or service). The diameter, or interior, of a …

DARPA TRIAD to apply AI/ML to phased array antennas for Military Wireless communications and radar systems

October 9, 2021 AI & IT, Electronics & EW Comments Off on DARPA TRIAD to apply AI/ML to phased array antennas for Military Wireless communications and radar systems

The demands on Wireless communications and radar systems have been continuingly increasing as the need for accuracy, efficiency, and more advanced metrics become increasingly important. Many new applications will only be possible with antennas that consume less power in a lower profile than traditional mechanically steered dish antennas. These requirements …

DARPA LTLT program developing Cryogenic microelectronics for future Supercomputers and data centres

Ground-penetrating radar for Autonomous driving, to detection of Tunnel, landmine and buried IEDs

October 6, 2021 Electronics & EW, Security Comments Off on Ground-penetrating radar for Autonomous driving, to detection of Tunnel, landmine and buried IEDs

Radar is an electromagnetic sensor used for detecting, locating, tracking, and recognizing objects of various kinds at considerable distances. It operates by transmitting electromagnetic energy toward objects, commonly referred to as targets, and observing the echoes returned from them. Energy is emitted in various frequencies and wavelengths from large wavelength radio …

3D Printing of Antennas and RF Electronics alleviate sourcing, manufacturability, and security concerns of defense and aerospace industries

October 2, 2021 Electronics & EW, Manufacturing Comments Off on 3D Printing of Antennas and RF Electronics alleviate sourcing, manufacturability, and security concerns of defense and aerospace industries

Additive manufacturing can reduce the time and material costs in a design cycle and enable the on-demand printing of customized parts. Recent advances in 3D printing technology now enable antennas and RF electronics to be designed and prototyped significantly faster than conventional manufacturing time scales. New multi-material 3D printers that …

DARPA GRYPHON developing high-performance microwave frequency source based on integrated photonics

September 28, 2021 Electronics & EW, Photonics Comments Off on DARPA GRYPHON developing high-performance microwave frequency source based on integrated photonics

In our information society, the synthesis, distribution, and processing of radio and microwave signals are ubiquitous in wireless networks, telecommunications, and radars. The current tendency is to use carriers in higher frequency bands, especially with looming bandwidth bottlenecks due to demands for e.g. 5G and the “Internet of Things.” “Microwave …

Militaries develop AI and machine learning enabled cognitive communications, Intelligence gathering and electronic warfare systems

September 26, 2021 AI & IT, Electronics & EW Comments Off on Militaries develop AI and machine learning enabled cognitive communications, Intelligence gathering and electronic warfare systems

Electronic warfare (EW) is one of the crucial aspects of modern warfare. EW receivers are passive systems that receive emission from various platforms that operate in the relative vicinity. The received signals are typically analyzed to obtain valuable information about characteristics and intentions of various elements that are presented in …

Hybrid marine propulsion system technology for smart ships

September 25, 2021 Electronics & EW, Energy & Propulsion Comments Off on Hybrid marine propulsion system technology for smart ships

Marine propulsion is the mechanism or system used to generate thrust to move a ship or boat across water. At present, 90% of the sea-going naval ship are diesel-powered. To achieve the safe upper limit for global warming of 1.5 degrees Celsius, ‘all ships designed and built today must operate in …

Millimeter wave (mmWave) power amplifiers enable mmWave Radios for 5G and Satellite Communications

September 16, 2021 Comm. & NW, Electronics & EW, Energy & Propulsion Comments Off on Millimeter wave (mmWave) power amplifiers enable mmWave Radios for 5G and Satellite Communications

Millimeter waves are electromagnetic signals with frequencies ranging from 30 to 300 GHz that correspond to wavelengths of 10 to 1 mm in the free space. Electromagnetic waves in the millimeter-wave band (with frequencies between 30 and 300 GHz, or wavelengths between 10 and 1.0 mm) have attractive characteristics. One of …

DARPA RNDMC program developing Distributed Beamforming Antennas across air, ground, and sea assets, to provide long range tactical communication robust against failure or attack

September 14, 2021 Comm. & NW, Electronics & EW Comments Off on DARPA RNDMC program developing Distributed Beamforming Antennas across air, ground, and sea assets, to provide long range tactical communication robust against failure or attack

DARPA, is proposing a new Mosaic Warfare strategy for evolving multidomain battlefield. Dr. Timothy Grayson, Director of the Strategic Technology Office is advocating for a “system of systems” approach that he’s calling mosaic warfare: the ability to piece together different systems to build new overarching warfighting capabilities. DARPA’s Strategic Technology …
