The agency developed and furthered much of the conceptual basis for the ARPANET—prototypical communications network launched nearly half a century ago—and invented the digital protocols that gave birth to the Internet. Such links are Defense Advanced Research Projects The Behavioral Learning for Adaptive Electronic Warfare (BLADE) program is developing the capability to counter new and dynamic wireless communication threats in tactical environments. © 2020 L3Harris Technologies, Inc. The most basic way that adaptive systems differ from earlier generations of EW systems is in the use of pre-programmed information. Due to the broad definition, there can be multiple technologies at play at once to instantiate and realize any particular adaptive EW system,” said Anthony Nigara, Director Electronic Warfare Mission Solutions.The worldwide proliferation of advanced digital radar and communication systems has caused a shift in the way traditional EW is executed and therefore developed the need for more advanced EW solutions. Adaptive EW provides distinct battlefield and operational advantages. BLADE is enabling a shift from today's manual-intensive lab-based countermeasure development approach to an adaptive, in-the-field systems approach. Traditional EW systems rely on pre-programmed databases of signal characteristics that describe the intended radars and/or communication systems that they are to identify and respond to. This is an official U.S. Department of Defense website sponsored by the Adaptive EW systems, in contrast, are able to utilize both pre-programmed signal characteristic information and what they observe in real-time from the radars and communication systems in order to complete their intended mission.Adaptive EW is mostly enabled today via software algorithms and enhancements, but there are potential benefits if an EW system utilizes a hardware architecture built specifically for adaptive EW. Early GPS receivers were bulky, heavy devices. In general, adaptive EW systems benefit from modern hardware that supports complex signal processing techniques and can handle a high level of complex processing operations in real-time. A deep dive into Harris solutions for different scenarios.The world of Electronic Warfare (EW) is rapidly evolving from the analog technologies developed in the 1960’s to small, handheld digital technologies such as “Adaptive EW is actually a very broad term that encompasses any application of artificial intelligence to the EW problem set. As Harris continues to innovate disruptive technologies, we are on the forefront of the next generation of EW – adaptive EW. The first two—Adaptive Radar Countermeasures (ARC) and Behavioral Learning for Adaptive Electronic Warfare (BLADE) are considered sister programs. One dominant operational benefit is that adaptive EW provides a direct response to adversarial threats, radar and communication systems to ensure EW systems remain current. endorsement by DARPA of non-U.S. Government sites or the information, provided consistent with the stated purpose of this website. BLADE is enabling a shift from today's manual-intensive lab-based countermeasure development approach to an adaptive, in-the-field systems approach. The appearance of hyperlinks does not constitute As communication and radar systems become more and more digital, and therefore software-defined, their behaviors and characteristics can be modified at a much more rapid pace than ever before, hence the need for EW systems that can adapt their response in real-time.Adaptive systems manage information differently than the analog technologies of the past. Adaptive EW is next generation innovation that will keep us one step ahead of our adversaries. management of DARPA. Both apply artificial intelligence, or AI, to EW systems. Agency.You are now leaving the DARPA.mil website that is under the control and The world of Electronic Warfare (EW) is rapidly evolving from the analog technologies developed in the 1960’s to small, handheld digital technologies such as Disruptor SRx.

Defense information, it does not exercise editorial control over all of products, or services contained therein. In 1983, DARPA set out to miniaturize them, leading to a much broader adoption of GPS capability. There are a surprising amount of benefits from relatively simple levels of adaptability in EW systems, Dahm said. ARPA research played a central role in launching the Information Revolution. As these adaptive EW systems get fielded and their capabilities are fully explored in operation and become a trusted technology by the EW community, adaptive EW has the potential to fundamentally alter how EW is conducted from development, to logistics, to operational employment.Harris continues to innovate technologies designed to connect, inform and protect our warfighters. Adaptive solutions, conversely, allow for basic operation in these environments, but are not capable of rapid understanding and countermeasures.

The program will achieve this by developing novel-machine learning algorithms and techniques that can rapidly detect and characterize new radio threats, dynamically synthesize new countermeasures, and provide accurate battle damage assessment based on over-the-air observable changes in the threat. Adaptive EW – the Future of Electronic Warfare. A potential longer-term benefit of adaptive EW is a decrease in the timelines for programming EW systems and the associated testing and re-validation required before a new capability can be deployed to the warfighter. use these sites as additional distribution channels for Department of “With cognitive electronic warfare, we’re imbuing these EW systems to observe a … However, upgrades to legacy EW systems and new generation systems are possible, although applicability and success varies by the particulars of the legacy EW system.The most important people in the world of EW continue to be the warfighter.
