Directed Energy Weapons Development Solutions

As the aerospace and defense industry adapts to evolving challenges, it prompts innovation of modern, high-tech weaponry. One of these emerging technologies is in directed energy weapons (DEW), which are designed to neutralize long-range targets with pinpoint accuracy using highly focused laser energy, delivering an edge over traditional weaponry to counter arising security threats across all domains. DEW can provide an endless magazine if enough power is available, thus eliminating the logistical problems of finite ammunition supplies and lowering the total cost per shot. Its speed-of-light delivery can neutralize distant targets while significantly reducing collateral damage. In addition, DEW offer a wide range of platform flexibility, capable of launching from large vehicles; ships at sea; fixed, land-based structures; and airborne platforms, among others.

Since DEW provide a unique response to rapidly emerging global threats, many industries and military branches are channeling research and development (R&D) efforts toward directed-energy technologies poised for near-term deployment. However, certain design issues must be addressed in order to achieve the high power levels necessary to support laser-based DEW deployment in critical security operations. To reach the optical powers required for laser weaponry, multiple laser modules are combined into a single beam, but the high optical intensity of each module over the fiber can generate Stimulated Brillouin Scattering (SBS) issues, which create a sizeable and destructive return loss.

With the ever increasing demand for higher data rates and lower power consumption, power and signal integrity are playing alarger role in the design of modern electronic devices. Demand from industry and consumers for higher throughput, more bandwidth and longer battery life mean stricter requirements and tighter tolerances on semiconductor and device design, test andmanufacturing. These emerging challenges cannot be addressed through simulation alone, driving the need for real worldevaluation and tolerance testing.

For over 30 years Noisecom has been designing noise generation devices and instruments for Carrier-to-Noise, jamming,multipath fading, satellite test and calibration across a wide variety of industries. Noisecom has a depth of experienceunmatched in the industry and works closely with technical end users to find the right product for their application withboth off the shelf and customized solutions. This experience and close links to customers and markets has led to thedevelopment of noise generators specifically designed for high speed data applications where real world power and signal integrity challenges exist.

Traditionally, the satellite industry has relied on geosynchronous earth orbit (GEO) satellites that take years to build and require very expensive launches to deliver them to orbit. Latency issues due to the distance of these orbits limit the ability of thesesatellites to be used for real-time communications like voice or live video transmissions. New technology is driving a wave ofinnovations and an evolution to smaller micro-sats deployed in low earth orbit (LEO) with reusable rockets delivering multiple satellites at a time with a single launch vehicle reducing deployment costs. These smaller satellites are deployed in mega-constellation arrangements to provide voice, video, imaging and data to commercial and military clients with higher data rates and lower latency than legacy GEO deployments.

Industry predictions show that large numbers of LEO micro-satellites will be launched due to performance and cost benefits ofusing the new technology. This increase in the number of satellite uplink and downlink stations will require systems to bedesigned to reject real-world RF interference from other uplink and downlink transmitters, as well as constellationcommunications between satellites as part of the relay network.

The development and deployment of 5G technology is changing the way wireless carriers and internet service providers think about meeting the ever increasing demands for higher data rates and more capacity from their customers. The rollout of 5G is being implemented in different ways and there is still a lot unknown about how homeowners, businesses and mobile customers will use emerging 5G networks and devices. Some providers see 5G as a push for increased bandwidth to mobile devices with currently used spectrum, below 6 GHz, while others see 5G as a fixed wireless access replacing legacy wired infrastructure operating in the millimeter wave range of the spectrum, above 28 GHz. Regardless of the approach and deployment the goal of 5G is to provide wireless data rates in excess of 1 Gbps and potentially over 20 Gbps.

As industry moves towards these higher speeds and use of new spectrum, new components and technology are required to build the radios necessary for 5G deployment. Devices are becoming more tightly integrated, more MIMO devices are being incorporated into designs, and high frequency phased array systems are being deployed. These new devices require new testing techniques in the lab, in production and in the field to ensure the high data rates being quoted are reliable in the real world when in the presence of real world noise and interference.
