Achieving Performance Advantages in Unmanned Systems

Unmanned Vehicle Systems (UVS) are reaching new levels of functionality and performance, and it’s not just for air vehicles either. Ground and underwater UVS programs are all taking advantage of the higher-performance computing platforms that are using highly integrated, multicore processors; faster and larger DDR and flash memory; as well as integrated I/O. Additionally, remote I/O subsystems are being implemented to distribute the processing power closer to the sensors and use packetized message passing — with multiple levels of security (MLS) — back to a smaller central vehicle and mission management computer.

COTS Embedded Systems and Link Budgets

The days of proprietary embedded computing systems in military systems are numbered. Proprietary systems, with the attendant vendor lock-in, tend to be platform specific, increasing the development and long-term maintenance costs. New platform: new design. The military has realized that this is an untenable approach.

Fiber Optic Multi-Sensing Platforms

Eventually, technology advances to the point where solutions that have been “good enough” for decades are no longer “good enough” for the innovations of today. The philosophy of “good enough” is widely applied when developing a new product or solution. Businesses have to make decisions about what new technology features will receive the most attention to keep projects within scope and completed on time.

A New Concept for Improving the Performance of Electrically Small Antennas

Using advances in the areas of multi-mode, closely coupled miniaturized radiators and artificially engineered materials, ultra-broadband, highly efficient, electrically small antennas were developed for operation in military communications systems. A low-profile UWB antenna was developed that is composed of two electrically small loops coupled together in their near fields. Each loop has a three-dimensional surface with a bent diamond-arm shape. Half of each loop placed on top of an infinite conducting ground plane is used in the design. Each loop is loaded with a top hat to reduce the lowest frequency of operation of the antenna.

Microwave Radiometer for Advanced Nanosatellite Control Systems

Microwave radiometers measure temperature, water vapor, and cloud ice in the atmosphere, since oxygen and water vapor naturally emit signals in the microwave portion of the electromagnetic spectrum. These signals are measured at different heights and are used to make 3D images of hurricanes, tropical storms, and thunderstorms. The NanoRacks-Microsized Microwave Atmospheric Satellite (NanoRacks-MicroMAS) measures temperature from molecular oxygen. NanoRacks-MicroMAS is a small, low-cost CubeSat containing a miniaturized microwave scanner that paves the way for future constellations of similar satellites, gathering more detailed, more frequent images of severe weather that impacts people on Earth. NanoRacks CubeSats are delivered to the International Space Station (ISS) already integrated within a NanoRacks CubeSat Deployer (NRCSD).

Secret Sharing Schemes and Advanced Encryption Standard

There are many secret sharing schemes and variations available to hide and reconstruct the given secret. Shamir’s Secret Sharing Scheme, making use of linear Lagrange interpolation on the dealer-generated polynomial, was used to reconstruct the secret from the stipulated threshold number of participants’ shares. Such a scheme had been widely analyzed by mathematicians and computer scientists for potential weaknesses in the reconstruction of the secret by an external eavesdropper.

SIPHER: Scalable Implementation of Primitives for Homomorphic Encryption

Prior to the Proceed program, the main challenges preventing practical demonstrations and use of Fully Homomorphic Encryption (FHE) were efficiency and scalability. At the start of the Program, the state-of-the-art FHE implementations were both inefficient and not scalable. Work in Scalable Implementation of Primitives for Homomorphic EncRyption (SIPHER) has brought FHE into the realm of practice, bringing several orders of magnitude runtime improvement, and resulting in FHE implementations that can be executed on single and multicore computers (including iPhones). Furthermore, implementation of an FHE hardware accelerator on a Virtex 7 Field Programmable Gate Array (FPGA) can speed up core FHE functions by over three orders of magnitude.

Analog-to-Digital Converter

The new EV12AD550 1.5GSps ADC from e2v (Chelmsford, UK) supports high dynamic range at 4.5GHz and S-band direct digitization, which enables space systems to avoid costly down conversion requirements. Future Synthetic Aperture Radar (SAR) Earth observation systems, for example, will be able to operate this ADC at up to 5.5GHz without the need for down conversion. The removal of down conversion stages reduces the weight, size and power consumption of the overall space system, helping to reduce expensive orbit costs.

Multiple Node Networking Using PCIe Interconnects

PCI Express (PCIe) interconnects, and how they can be used to support multiple node low latency data transfers over copper or optical cables, is gaining momentum in embedded computing solutions. Many current “out-of-the-box” solutions are being used to interconnect standard Intel-based servers in traditional commercial computer environments to shared I/O devices on Windows or Linux operating systems. Now emerging is the use of PCIe to provide box-to-box external data paths between rugged embedded systems as well as for the internal data path in backplane architectures, such as VPX. Why is this trend developing, and what implementation challenges, as well as possible solutions, is the industry seeing through the use of PCIe?

Analyzing Radar Signals with Demodulation

In the electronic warfare milieu, one of the most common RF applications is that of radar systems. Radar, which uses RF energy to determine the range, angle, and/or velocity of objects, detects aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain, among other things. An oscilloscope's demodulation math function is very helpful in analysis of radar signals, so let's look at a couple of examples of how to approach such measurements.
