The principle of RF is very simple, it is characterized by the radiation of microwaves (radio waves with a wavelength of 1 meter to 1 millimeter), also known as radio waves or microwave weapons. RF weapons consist of ultra-high-power microwave transmitters, large antennas, and other supporting equipment such as power supplies. The structure of RF weapons is similar to the transmitting part of radar, but the energy it radiates is a hundred to ten thousand times larger than that of radar. Ultra-high power microwave transmitter can be realized by single or multiple microwave tubes, so it is a large-scale equipment. Large antenna to ultra-high power microwave transmitter output energy convergence in a narrow beam, with very high power irradiation target, through the thermal effect or electromagnetic field induction effect to kill and maim personnel or destroy the target internal electronic equipment.
