Electronic signals play a very important role in modern warfare. The stability of the signal is important for combat. Countries that study how to protect the stability of their signals will find ways to affect the signals of other countries. According to a report by the South Korean government, North Korea has developed a powerful jammer that can interfere with GPS (Global Positioning System) satellite signals within a range of "more than 100 kilometers." The news agency said the news about the GPS jammer was included in the report handed over to the National Defense Committee of the South Korean Congress this week.
The South Korean capital is about 50 kilometers from the border area, so GPS Jammers with such a range may destroy or eliminate GPS signals in and around Seoul. The cities and regions along the border are full of military installations and equipment, many of which use GPS satellite positioning signals. The US Navy has entered the final stage of development of the next-generation jammer (NGJ) pod, which will replace the ALQ-99 that has been used since the Vietnam War. The new electronic attack pod is matched with the advanced electronic attack technology developed by Raytheon, which combines powerful agile beam interference technology with the latest electronic electronic technology.
The AN/ALQ-99 tactical jamming system is currently integrated into the US Navy and Marine Corps EA-18G GROWLER and EA-6B Prowler aircraft. Both aircraft are currently in service, but only the F/A-18G is expected to be operational in the mid-2020s. Therefore, the new pod is specially developed for growers. He said that in terms of isotropically radiated power, the next-generation jammer "is about ten times what we usually spend on ALQ-99." In terms of capacity, "Baseball Field" can handle four times the number of tasks and has the ability to go from "goal to goal to goal". The next air battle will be conducted on the electromagnetic spectrum," Major General Michael Manazil, commander of the naval air warfare, told MPs in April and briefly introduced the status of the next generation of the sound. The next generation of jammers have a higher equivalent Omnidirectional radiated power, more distribution, digital-based waveform modulation, coherent countermeasures, wide-band spectrum, clear spectrum output and open structure to deal with these factors.
