Photonic ADCs have removed the bottlenecks of bandwidth limitations and timing jitter of electronic analog-to-digital converter (ADC)

May 23, 2020 Electronics & EW, Photonics Comments Off on Photonic ADCs have removed the bottlenecks of bandwidth limitations and timing jitter of electronic analog-to-digital converter (ADC)

The performance of digital receivers used in modern military radar, communication, and surveillance systems is often limited by the performance of the analog-to-digital converter (ADC) used to digitize the received signal. Ultrafast ADCs are critical in military applications such as military software-defined radio, radar, and electronic counter-warfare (ECW) that require …

Militaries race to develop Quantum radar that would render Stealth Aircraft Obsolete, monitor Ballistic missiles to low altitude satellites

May 9, 2020 Electronics & EW, Quantum Comments Off on Militaries race to develop Quantum radar that would render Stealth Aircraft Obsolete, monitor Ballistic missiles to low altitude satellites

The utility of Modern high frequency Radars have become degraded due to innovation in stealth that resulted include unusual shapes that deflect radar waves—like the US B-2 bomber’s “flying wing” design (above)—as well as carbon-based materials and novel paints. China and Russia have since gotten stealth aircraft of their own, …

Structural electronics to disrupt the automotive and aerospace sectors by replacing dumb components with smart materials, smart skin, load-bearing parts, and e-textiles

May 6, 2020 Electronics & EW, Industry Comments Off on Structural electronics to disrupt the automotive and aerospace sectors by replacing dumb components with smart materials, smart skin, load-bearing parts, and e-textiles

The term, structural electronics (SE), refers to a next-generation based electronics technology, which involves the printing of functional electronic circuitries, across irregular-shaped architectures. SE is expected to replace bulky load-bearing structures within a circuitry with smart electronic components that can conform to complex shapes for ensuring optimum space utilization. SE …

US DOD developing Cryogenic Signal Intelligence (SIGINT) systems for future Electronic Warfare

May 5, 2020 Electronics & EW Comments Off on US DOD developing Cryogenic Signal Intelligence (SIGINT) systems for future Electronic Warfare

Cryogenics is the study of the production of extremely cold temperatures and is a field of science that looks at what happens when materials, whether metals or gases, are exposed to very low temperatures. The range of temperature associated with cryogenics does tend to vary but is usually associated with …

Antennas breakthroughs enabling IoT, 5G, WiFi, Wearables, Military communications, radar, and electronic warfare.

May 4, 2020 Electronics & EW, Military Comments Off on Antennas breakthroughs enabling IoT, 5G, WiFi, Wearables, Military communications, radar, and electronic warfare.

Antennas are our electronic eyes and ears on the world. They play a very important role in mobile networks, satellite communications system, military communications, radars and electronic warfare by transforming a Radiofrequency ( RF) signal, traveling on a conductor, into an electromagnetic wave in free space and vice versa. The …

DARPA SSPARC developed spectrum-sharing technologies between military radars and communication systems for assured access to contested electromagnetic environment

April 27, 2020 Electronics & EW Comments Off on DARPA SSPARC developed spectrum-sharing technologies between military radars and communication systems for assured access to contested electromagnetic environment

Spectrum congestion is a growing problem. It increasingly limits operational capabilities due to the increasing deployment and bandwidth of wireless communications, the use of net-centric and unmanned systems, and the need for increased flexibility in radar and communications spectrum to improve performance and to overcome sophisticated countermeasures. Ongoing wireless …

Propulsion motors are enabling stealthy warships and submarines propelled with an electric propulsion system

April 26, 2020 Electronics & EW, Navy Comments Off on Propulsion motors are enabling stealthy warships and submarines propelled with an electric propulsion system

Navies of various countries have announced making their warships and submarines propelled with an electric propulsion system. Instead of driving the ship’s propellers directly, diesel engines turn electric generators, which in turn power electric motors that drive the propellers. This arrangement enables diesels to be placed away from the shafts and …

NATO refocussing on development of Electronic Warfare to match sophiticated capabilites of its adversaries

April 19, 2020 Electronics & EW, Geopolitics Comments Off on NATO refocussing on development of Electronic Warfare to match sophiticated capabilites of its adversaries

For NATO forces, the Electromagnetic spectrum (EMS) is an essential part of military operations, so much so that many Allied leaders now see the EME as an operational environment and a part of the battlespace where friendly forces manoeuvre in time, location, and spectrum to create electromagnetic effects in support …

Neutron Beams can detect Nuclear Warheads and disable them

March 28, 2020 Electronics & EW, Military Comments Off on Neutron Beams can detect Nuclear Warheads and disable them

Despite making reductions in their arsenals, both the USA and Russia have extensive and expensive programmes under way to replace and modernize their nuclear warheads, missile and aircraft delivery systems, and nuclear weapon production facilities. The Nuclear Race between US, Russia, and China through their continuous modernization of all the …

Heterogeneous Integration Technology enhance capability of military RADAR, communications, imaging and sensing systems, DARPA’s DAHI, and CHIPS led its development

March 19, 2020 Electronics & EW, Material Comments Off on Heterogeneous Integration Technology enhance capability of military RADAR, communications, imaging and sensing systems, DARPA’s DAHI, and CHIPS led its development

Modern warfare is increasingly dependent on microelectronics capabilities that sense the environment, convert the signals into data streams, process the information, and generate a response. In this sense, Aerospace and Defense (A-D) systems are quite similar to commercial systems that perform communications and computations, while taking advantage of the advancement …
