Military sensor and signal processing technologies are going through revolutionary improvements, and offer to bring big enhancements to applications like radar, electronic warfare (EW), signals intelligence (SIGINT), high-performance edge computing, and anti-submarine warfare (ASW).
Big enablers that have been coming online over the past year or so include artificial intelligence (AI) and machine learning for so-called smart sensors, open-systems industry standards like the Sensor Open Systems Architecture (SOSA), new architectures for field-programmable gate arrays (FPGAs), information security, fast networking over copper and optical interfaces, and fast A/D and D/A conversion.
With these enhancements, systems designers can process more data than ever before; reduce, size, weight, and power consumption (SWaP); free-up slots in the embedded computing enclosure for additional capabilities; and place high-performance sensor and signal processing as close to receiver antennas as possible in SWaP-constrained applications like unmanned vehicles.
“There’s more data, more processing for the data ... it’s all more, more, more,” says David Jedynak, chief technology officer at embedded computing specialist Curtiss-Wright Defense Solutions in Ashburn, Va.
The influence of SOSA
The SOSA standard, supervised by the Open Group in San Francisco, aims generally at high-performance embedded computing, but is being developed specifically with signal processing in mind. The standard seeks to tame the proliferation of open-systems VPX standards and create a manageable set of interoperability guidelines for aerospace and defense systems to enable a broad variety of components from separate vendors to work together easily.
