Radio jamming is the deliberate blocking of or interference with wireless communications. [1] [2] In some cases, jammers work by the transmission of radio signals that disrupt telecommunications by decreasing the signal-to-noise ratio. [3] The concept can be used in wireless data networks to disrupt information flow. [4]

The THOR III is man-portable, counter-radio-controlled improvised explosive device (IED) jammer built by Sierra Nevada Corp, designed to counter specifically Radio Controlled Improvised Explosive Devices (RCIED). [2] It was employed by the U.S. Army, U.S. Marine Corps, and partnered Afghan National Army soldiers in Afghanistan.

2023年10月10日 · Electronic jamming, a form of EW that uses radio signals to interfere with an enemy's radar, is another modern warfare tool. “Jamming is intended to degrade the ability of radars or radios to perform their tasks, or even prevent them from doing so altogether,” writes Defense Advancement .

Electronic warfare (EW) and jamming systems are used to detect, intercept, and disrupt enemy communications and radar signals, protecting military personnel and assets. These systems target adversary technologies using electromagnetic energy and include electronic attack measures such as jammers and countermeasures like radiofrequency weapons.

2024年12月4日 · At its simplest, jamming is intended to degrade the ability of radars or radios to perform their tasks, or even prevent them from doing so altogether. The jamming process also harnesses radio signals but does so in such a way as to attack these systems. Put simply, jamming equipment uses artificially created radio interference offensively.

2023年10月10日 · The Army’s recently awarded dismounted electronic jammer stems from existing technology that has been used by special operations forces — significantly shortening the timeline for fielding the equipment to conventional soldiers.

Diferent types of jammers can cause varying degrees of interference, but the use of powerful military jammers are becoming more prevalent. This article provides an overview of the emergence, development, and scale of the GPS jamming phenomena.

2023年8月10日 · NGJ-LB will be a high-powered and advanced AEA system. L3Harris’ jamming pod enables extended stand-off jamming, covers a broad spectrum of frequencies to service U.S. Department of Defense-wide EW demands, and will be more sustainable than the current system.

2025年1月7日 · The Naval Air Systems Command (NAVAIR) has disclosed on Jan. 6, 2025, that the U.S. Navy declared initial operational capability (IOC) for the AN/ALQ-249 Next Generation Jammer Mid-Band (NGJ-MB ...

2025年1月27日 · The fibre-optic cable drone is immune to the jammers, however, because it operates on a wired connection instead of radio signals. In this image released by Ukraine's Ministry of Defence, a fibre ...
