US, Israel and India require new Tunnel Detection and neutralization technologies to stop drug and weapon smuggling, human trafficking, and cross border terrorism

February 21, 2021 Electronics & EW, Security & Threat Management Comments Off on US, Israel and India require new Tunnel Detection and neutralization technologies to stop drug and weapon smuggling, human trafficking, and cross border terrorism

Criminals, terrorists and military have been using tunnels since long time to evade detection as surface based detection methods are ineffective underground . Indian Border Security Force (BSF) troopers in Nov 2020 discovered an underground tunnel on the international border at Regal area in J&K`s Samba district, officials said. As …

DARPA GRIT program developing compact, tunable Gamma ray source for advanced accelerator technology, high-energy laser systems, and new x-ray and gamma ray detectors

February 13, 2021 Electronics & EW, Manufacturing, Security & Threat Management Comments Off on DARPA GRIT program developing compact, tunable Gamma ray source for advanced accelerator technology, high-energy laser systems, and new x-ray and gamma ray detectors

Gamma rays are ionizing electromagnetic radiation, obtained by the decay of an atomic nucleus. Gamma rays are given off by stars, and by some radioactive substances. Gamma-rays travel to us across vast distances of the universe, only to be absorbed by the Earth’s atmosphere. Different wavelengths of light penetrate the Earth’s …

Surface-acoustic-wave (SAW) and bulk-acoustic-wave (BAW) Filters will be disruptor in the military RF and microwave industries

February 13, 2021 Electronics & EW, Industry & Market Dynamics Comments Off on Surface-acoustic-wave (SAW) and bulk-acoustic-wave (BAW) Filters will be disruptor in the military RF and microwave industries

The complexity of current 4G/5G phones comes from the need to cover multiple bands. Modern modems like the ones used in mobile phones are compatible with multiple transmission bands, including 3G, 4G LTE, Wi-Fi, and Bluetooth. The radio frequency front-end (RFFE) section of cellphone includes components like antennas, LNAs, filters, …

Miniaturized RF passive components like filters, inductors and capacitors required for future 5G and IoT requirements

February 4, 2021 Electronics & EW, Manufacturing Comments Off on Miniaturized RF passive components like filters, inductors and capacitors required for future 5G and IoT requirements

The RF design consists of passive as well as active components. The inductors, capacitors, and resistors are one of the three passive elements that are the foundations of all electronics. The discrete and passive components are an integral part of the design; from front-end antenna matching to tight-tolerance mixers, oscillators, …

RF/Microwave Switching Technologies

January 29, 2021 Comm. & Networking, Electronics & EW Comments Off on RF/Microwave Switching Technologies

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 or microwave switch is a device to route high frequency …

DARPA thrust in Terahertz electronics for future military wireless and sensing

January 22, 2021 Comm. & Networking, Defense & Military, Electronics & EW Comments Off on DARPA thrust in Terahertz electronics for future military wireless and sensing

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 …

Passive and active multistatic radars capable of detecting stealth fighters and guiding missiles to destroy them

January 14, 2021 Air Force & Aviation, Electronics & EW, Geopolitics, Strategy & Technological Rivalries Comments Off on Passive and active multistatic radars capable of detecting stealth fighters and guiding missiles to destroy them

Stealth technology has proven to be one of the effective approaches to enhance the survivability of Aircrafts. Aircraft/helicopter designers are making them stealthier by reducing their signatures; viz. visual, aural, infrared (IR), and RADAR cross section. Advancements in stealth technologies, as demonstrated by the very low RCS of stealth aircraft …

DARPA’s ARC and BLADE developed Cognitive and Adaptive Electronic warfare Systems to Counter dynamic wireless communication and radar threats

January 10, 2021 AI & IT, Electronics & EW Comments Off on DARPA’s ARC and BLADE developed Cognitive and Adaptive Electronic warfare Systems to Counter dynamic wireless communication and radar threats

Electronic warfare provide means to counter adversary’s radar and communication systems while protecting one’s own systems through Electronic Attack (EA), Electronic Protection (EP) and Electronic Support (ES). Jamming systems still rely on classified databases of known emitter signals. As radars emit energy, an onboard receiver characterises the incoming signal and and …

Cognitive and Adaptive Radar technologies can counter advanced electronic threats

January 7, 2021 AI & IT, Electronics & EW Comments Off on Cognitive and Adaptive Radar technologies can counter advanced electronic threats

RADAR offers special advantages with respect to other types of sensors including all-day, all-weather operations, long detection distance and, depending on the frequency used, penetration. Moreover, radar can often be carried by a number of platforms, spanning from classic naval and airborne to more recent space-borne, UAVs, such as drones, …

Weapon Locating Radars (WLR) that can track artillery rounds, rockets, mortar shells and unguided rockets, have been developed by NATO, China and India

January 3, 2021 Army & Land, Electronics & EW, Weapons & Munitions Comments Off on Weapon Locating Radars (WLR) that can track artillery rounds, rockets, mortar shells and unguided rockets, have been developed by NATO, China and India

Weapon Locating Radars (WLR) are primarily used to detect and locate enemy Artillery units by tracking the trajectory of incoming rounds. They can also provide fire correction of friendly artillery units. WLRs usually can also track mortar shells and unguided rockets. Some WLRs also have limited missile tracking and Air …
