Greater processing power, advanced filtering, and better signal rejection are among the digital signal processing enabling technologies for electronic warfare projects today.
Electronic attacks have been a part of warfare since the radio transmitter was invented in the 1890s. The invisible electromagnetic spectrum enables users to listen to music, cook food, and view hidden injuries via X-ray.
Today it’s also another type of battlefield.
Before warfighters and vehicles make a move, they need to ensure the avenue is open not only on the physical battlefield, but also on the electromagnetic spectrum. All branches of the military can gain a big advantage by dominating the electromagnetic spectrum.
Electronic warfare (EW) -- jamming or spoofing an enemy's communications and RF sensor systems -- has some crossover with other technologies such as radar or directed-energy electromagnetic weapons. However, it also has its own equipment, technology needs, and unique standards. Spectrum-dependent systems can be found across air, land, and sea domains, plus cyber.
