In April  2017, the U.S. military dropped the most powerful non-nuclear bomb ever used in combat on a tunnel complex in Afghanistan’s Nangarhar province. The airstrike targeted the Islamic State’s Khorasan branch. The use of the GBU-43/B Massive Ordnance Air Blast weapon, the so-called “Mother of All Bombs,” highlighted the …

In recent weeks, concern over the emergence of a novel coronavirus in China has grown exponentially as media, experts and government officials around the world have openly worried that this new disease has the potential to develop into a global pandemic. As the ongoing coronavirus outbreak centered in China has spread …

Security forces require effective ground ISR technologies that can overcome these challenges and provide effective situational awareness. One of the technologies useful in such situations is through-wall imaging which apply radio frequency (RF) and other sensing modes to penetrate wall materials and optimally estimate the terrorists hiding in other  rooms …

Lidars (Light Detection and Ranging) are similar to radars in that they operate by sending light pulses to the targets and calculate distances by measuring the received time.  The  key advantages of  LIDAR is  its superior accuracy and its ability to see through masking items, such as leaves, trees, and …

Recently the Directed Energy Weapons (DEWs), especially laser DEWs are being developed as non lethal weapons. DEW is a system  that uses Directed Energy primarily as a means to incapacitate, damage, disable or destroy enemy equipment, facilities and/or personnel. Directed energy has the potential to yield cost effective weapons that …

The threats of chemical, biological, radiological, nuclear and explosive (CBRNE) hazards continue to advance. CBRN weapons are some of the most indiscriminate and deadly weapons in existence today, with capability to affect large population in wide geographical area and in short time. The release of Chemical, Biological, Radiological and Nuclear …

Search and Rescue (SAR) is receiving a lot of attention recently due to several high-profile incidents on land, in the air and at sea. Flight MH370 left Kuala Lumpur was bound for Beijing in March 2014 when it disappeared, with 239 people on board. Even after the largest and most …

Flight MH370 left Kuala Lumpur was bound for Beijing in March 2014 when it disappeared, with 239 people on board. Even after the largest and most expensive search in aviation history, to date, neither any confirmed debris from the aircraft nor any survivors have been found. A four-year deep sea …

The quantum cascade laser is a special kind of semiconductor laser, usually emitting in the mid- and long-wave infrared bands. Such a laser operates on laser transitions not between different electronic bands but on intersubband transitions of a semiconductor structure.  Their wide tuning range and fast response time allow for faster …

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.   Over the past decade, optical …
