A type of DEW [directed-energy weapon] that uses RF [radio-frequency] energy to upset or damage the electronics of a target.  5, fiche 2, Anglais, - radio%20frequency%20weapon

Record number: 2, Textual support number: 1 CONT

RF weapons are usually divided into two categories : high power microwave(HPM) weapons and ultrawideband(UWB)(or video pulse) weapons.  6, fiche 2, Anglais, - radio%20frequency%20weapon

Record number: 2, Textual support number: 2 CONT

The primary distinction between RF weapons and more conventional EW systems is that RF weapons actually affect the electronics and not just the electronic environment, thereby causing temporary or permanent electronics failure that persists even after the RF beam has been turned off. RF weapons will mainly target receiver systems with in-band HPM [high-power microwave] radiation or computer systems with ultrawideband impulses.  5, fiche 2, Anglais, - radio%20frequency%20weapon

Record number: 2, Textual support number: 3 CONT

In a radio-frequency weapon, electromagnetic radiation at wavelengths similar to that of radar is aimed at a target by means of an antenna. The principal effect would be to damage or destroy the electronic circuits of a missile.  7, fiche 2, Anglais, - radio%20frequency%20weapon

La tecnología de banda ultraancha, típicamente caracterizada por una radiación de muy baja potencia en una banda de radiofrecuencia muy ancha, podría facilitar toda una serie de aplicaciones de comunicación, medición, localización, medicina, vigilancia e imágenes beneficiosas para diversas políticas comunitarias, incluidas las de la sociedad de la información y mercado interior. Dadas estas circunstancias, es importante establecer unas condiciones reguladoras que favorezcan el desarrollo de mercados económicamente viables para las aplicaciones de tecnología de banda ultraancha a medida que vayan surgiendo oportunidades comerciales.  3, fiche 3, Espagnol, - banda%20ultraancha

Record number: 3, Textual support number: 2 CONT

[...] la banda ultra ancha utiliza una energía muy baja, ofrece una banda mucho más ancha y permite reutilizar frecuencias asignadas con otros usuarios sin muchas interferencias; también tiene sus desventajas, sólo opera en rangos de hasta 10 metros y los dispositivos tienen que ser monitorizados de cerca para asegurarse de que no utilizan mucha energía [...]  2, fiche 3, Espagnol, - banda%20ultraancha

UWB weapons would generate RF [radio-frequency] radiation covering a wide frequency spectrum... with limited directivity. Because of the UWB weapon's low-energy spectral density and directivity, permanent damage to electronic components would be very difficult to achieve, except at very short ranges.  1, fiche 4, Anglais, - ultrawideband%20weapon
