Leonidas car mounted high-power microwave system. Not long ago, a video released by a company in the United States attracted attention from the outside world. In a demonstration, the company successfully disabled a fiber optic guided drone using its developed Leonidas vehicle mounted high-power microwave system. This move means that the "fiber optic machines" that are immune to traditional electronic detection, deception, and interference may face new challenges. Fiber optic aircraft "is the abbreviation for fiber optic guided unmanned aerial vehicles. Unlike drones operated through radio frequency control links, a distinct feature of a "fiber optic machine" is that it drags a thin, long, and lightweight fiber optic cable behind it. Don't underestimate this fiber optic cable, its function is not insignificant. On the one hand, the signals transmitted and received by the "fiber optic machine", including the command signal, operate inside the fiber optic system, making it difficult for the outside world to conduct electronic detection, deception, and interference on the "fiber optic machine" like unmanned aerial vehicles that deal with RF signal manipulation; On the other hand, these signals propagate at the speed of light inside the fiber optic cable, ensuring that the pilots can obtain real-time battlefield information and maintain clear images. Due to the above advantages, "fiber optic machines" have become popular in recent years. At the same time, countries are also studying how to counteract it. Since countermeasures cannot be carried out like drones that deal with radio frequency signal manipulation, some countries have begun to explore methods of using kinetic energy to kill or directed energy to attack "fiber optic aircraft". The Leonidas car mounted high-power microwave system developed by this American company is one of the new advances in directed energy attack on "fiber optic machines". Unlike lasers, microwaves have certain advantages in countering drones - they can use energy fields to disable target electronic devices (mainly by overloading and burning electronic components), and are particularly adept at dealing with group targets. The Leonidas car mounted high-power microwave system, with the help of software defined architecture and high-power electromagnetic technology, also has the ability to control the waveform, frequency, power, direction, and duration of electromagnetic energy in real time, focusing energy on a single point to attack individual targets in a group. In addition to the company in the United States, some companies in other countries are also developing high-power microwave systems. For example, the Dragon electromagnetic anti UAV system recently demonstrated by Türkiye also has the ability to deal with the threat of bees. However, most of these high-power microwave systems are still in the testing stage. If the relevant technologies mature and are deployed on the battlefield in the future, such weapons are likely to become the new nemesis of "fiber optic machines". (New Society)
