Sensors are being used in growing numbers in a variety of military data acquisition systems. Complex, high-end suites of sensors are being deployed in next-generation components of the Future Combat Systems program, while simpler, low-end devices are found in logistics management and material inventory and control.
Today’s military data acquisition and precision machine control applications demand faster microprocessors, better performance and higher memory and packaging densities. In response, intelligent control subsystems are utilizing sophisticated sensors, or integrated suites of sensors, for manned and unmanned applications.
As the data converters used in military applications must operate faster and at greater resolution, the digital domain is moving closer to the antenna/sensor array. In response, two different approaches to DSP architectures are being used, sometimes in combination: moving the data faster, and/or moving the DSP hardware.
On the Softer Side Safety-Critical Software Standards
Without Multiple Independent Levels of Security (MILS), integrators have to implement each level of security function individually on a separate processor. The MILS architecture on a single processor is both cost-effective and possible with today’s technology.
Ada boasts a respected legacy in safety-critical mil/aero apps. An emerging 2005 rev of the language improves on that legacy, while overshadowing the advantages offered by more modern programming languages.
Flash solid-state drives have achieved performance and capacity levels well on par with magnetic hard disks. Secure erase capabilities help seal the deal.
When shock/vibration, altitude, humidity and temperatures are high, rotating hard disks become a real weak link. Flash disks offer a rugged, secure alternative.
The small volumes on the military market are a mismatch to the high volumes and fast lifecycles that drive the semiconductor industry. Military system designers must look to specialist vendors and redesign options to keep pace.
