Technical Field

Background

The electronic interference device is generally divided into an active electronic interference device and a passive electronic interference device, wherein the active electronic interference is to transmit or forward electromagnetic waves of a certain form by using a special interference transmitter so as to disturb or destroy the work of the electronic equipment and the system of the other party. The carrier frequency, power and modulation mode (interference pattern) of the transmitted interference signal are selected according to the type, working frequency and technical system of the electronic equipment to be interfered. Passive electronic interference is to use foil strip, reflector or electric wave absorber which do not emit electromagnetic wave to reflect or absorb the electric wave emitted by the electronic equipment of the other party, so that the efficiency is weakened or destroyed. Such interference is mainly used for interfering with electronic devices that operate by receiving reflected electric waves, such as radar and laser ranging devices.

Therefore, there is a need for an electronic interference device to protect the safety of country sensitive geographic location information, so as to interfere and block the GNSS satellite navigation system from receiving signals, so that the GNSS satellite navigation system loses its navigation and positioning functions in the country sensitive geographic location.
