Defeating Commercial Drone Threats with Open-Source SDR
With the emergence of highly capable, low-cost, wirelessly controlled drones, bad actors can easily execute disruptive operations.

Conventional reconfigurable electrical and radio frequency (RF) structures commonly used in applications involving real-time reconfigurability in response to fast varying...

The design of avionics systems must balance several factors. First, engineers want to increase the performance of the systems installed in aircraft or spacecraft. Second, they want...

A centralized IMA approach offers several advantages.

Sandia National Laboratories’ (Albuquerque, NM) Radar Intelligence, Surveillance and Reconnaissance (ISR) systems enable a new product paradigm in radar capabilities...

SPYNEL sensors are passive wide area surveillance systems with automatic intrusion detection and tracking capabilities. The 360° thermal sensors offer 24/7 situational awareness by detecting and tracking...

As the demand for greater control and functionality increases, position-sensor-instrumented hydraulic cylinders are becoming more important in the heavy industry, mobile equipment, and subsea...

As drones become more commonplace, the need to secure facilities from the high-definition cameras and potential dangerous payloads has caused a rapid growth of counter-drone technologies.

There have been several news headlines lately about offenders pointing commercial lasers at helicopters or police personnel, temporarily blinding and distracting them. An increasing number of...

More and more aerospace applications are incorporating fiber optics technology into their designs due to its many advantages over copper. The thinner fiber solutions provide higher speed over a...

Laser Detecting Systems

Whether engaged in an asymmetric fight with an insurgent or a conventional battle with a “near-peer” adversary, today's battlefield presents combatants with significant challenges. Rapidly advancing technology and...

Transmitting and receiving radio signals between spacecraft in deep space is a snap compared with getting those signals back to Earth, especially when the spacecraft is 120 billion miles away.

A single antenna can be used for both transmission and reception. To accomplish this, the transmission must be isolated from the reception. In Figure 1, a radio frequency...

The recent surge in demand for adaptive cruise control (ACC) and commercial autonomous vehicles has drawn a lot of attention to these innovative applications. Based on pulsed laser...

That was the challenge posed to Gentex by Boeing. Window shades typically do the job on an airplane, but they’re cumbersome to operate, expensive to maintain, and do little to reflect the...

Interference mitigation is crucial in modern radio frequency (RF) communications systems with dynamically changing operating frequencies, such as cognitive radios, modern military radar, and electronic warfare...
