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 increased lethality of weapon systems have forced the military to develop and deliver more effective technologies to protect our air and vehicle crews. One such critical technology – laser detecting systems – is designed to detect and alert crews to laser-aided threats.

New Products: April 2018 Aerospace & Defense Technology

RF Cable

PIC Wire & Cable® (Sussex, WI), a Division of The Angelus Corporation, recently announced the launch of its new RFMATES ® ULTRALITE UH25107 cable. UH25107 is a 50 ohm RF aerospace cable that is highly shielded, light and flexible. The cable's sophisticated design yields low loss characteristics that make it a robust solution for systems requiring a low dB loss budget for antenna runs, like SATCOM and Iridium systems.

Designing for Compressive Sensing: Compressive Art, Camouflage, Fonts, and Quick Response Codes

Compressive sensing (CS) is a relatively new field that has caused a lot of excitement in the signal processing community. It has superseded Shannon's time-honored sampling theorem, which states that the sampling rate of a signal must be at least twice its highest frequency. In CS, the necessary sampling rate depends on the sparsity of signal, not its highest frequency, reducing sampling requirements for many signals that exhibit natural sparsity. This compression happens on the hardware level, allowing systems to be designed with benefits ranging from increased resolution and frame rates to decreased power consumption and memory usage. Despite this enthusiasm for CS and the large quantity of research being performed, the number of commercial systems that use CS is relatively few. The problem of designing a CS strategy that increases functionality while actually reducing overall system cost has not been solved in many areas. This is a developing field where not only are new applications for CS still being developed, but also fundamental aspects of CS theory are still evolving.

Calculation of Weapon Platform Attitude and Cant Using Available Sensor Feedback

When firing artillery, there is typically a maximum angle that the platform cannot exceed relative to the Earth plane. This is due to the large recoil forces involved and the risk of destabilizing the platform the weapon is mounted to. Mobile systems are particularly sensitive to this as the attitude of the platform relative to Earth is constantly changing. A simple solution is to add pitch and roll sensors directly to the platform. However, many mobile systems already have an assortment of sensors that can be used to calculate the platform attitude.

Designing With Plastics for Military Equipment

U.S. soldiers carry loads of equipment and protective gear that can weigh anywhere from 45 to 130 pounds. This is more than enough to quickly tire even the most well-conditioned personnel, contributing to reduced mobility and impaired decision-making that could result in casualties.

Engine Air-Brakes

Airplanes, one of humanity's greatest inventions, evoke feelings of awe and amazement for most people, unless you live uncomfortably close to a major airport, in which case the feeling may become annoyance and irritation. Constant aircraft noise causes sleepless nights, stress and other health issues, reducing quality of life.
