El Comando de Desarrollo de Capacidades de Combate del Ej\u00e9rcito de EE.UU. (DEVCOM), el Laboratorio de Investigaci\u00f3n del Ej\u00e9rcito y Virginia Tech, desarrollaron un algoritmo\u00a0para que los radares funcionen sin problemas en entornos de espectro limitado,\u00a0en ambientes congestionados por 4G LTE comerciales y los futuros sistemas de comunicaciones 5G.<\/p>\n
ADELPHI, Md.<\/strong> — A new machine learning approach could improve radar performance in congested environments.<\/p>\n Researchers from the U.S. Army Combat Capabilities Development Command, now known as DEVCOM, Army Research Laboratory<\/a> and Virginia Tech<\/a> developed an automatic way for radars to seamlessly operate in congested and limited spectrum environments created by commercial 4G LTE and future 5G communications systems.<\/p>\n \u201cFuture implementations of this algorithm into Army legacy and developmental radars will provide unprecedented spectrum dominance for Soldiers,\u201d said Army researcher Dr. Anthony Martone<\/a>. \u201cThis will enable Soldiers to use their radars for problems such as tracking incoming targets while mitigating interference to maximize target detection range.\u201d<\/p><\/blockquote>\n The researchers examined how future DOD radar systems will share the spectrum with commercial communications systems. The team used machine learning to learn the behavior of ever-changing interference in the spectrum and find clean spectrum to maximize the radar performance. Once clean spectrum is identified, waveforms can be modified to best fit into the spectrum.<\/p>\n This research is part of a larger defense program to implement adaptive signal processing and machine learning algorithms onto software-defined radar platforms for autonomous real-time behavior.<\/p>\n \u201cWith development of this algorithm, this capability is fast-tracking from a concept to a Defense program of record in less than eight years,\u201d Martone said. \u201cThis is a notably expedited cycle compared to the more typical 30-year cycle, which will more quickly provide secure communications for Soldiers.\u201d<\/p><\/blockquote>\n The team is leading future research and development efforts to make cognitive radar possible and sharing new research areas within the radar community, with the intent to continue development using more advanced software-defined radar platforms.<\/p>\n
