It transmits electromagnetic wave carrier frequency and the carrier frequency of the interfered signal is the same, so together with the receiver to receive and amplify the demodulation (restore), the interference signal and the interfered signal at the same time in the receiving terminal. This is like loading fake goods (like jamming signals) of the transport vehicle and loading real goods (like jamming signals) of the transport vehicle model appearance (carrier frequency) is the same, the receiver only recognize the car does not look at the goods, the results of the real and fake goods together with the owner of the goods there, the electronic jamming power is strong enough, over the jamming signals, can achieve the purpose of the jamming.
Jammer:
Terrestrial satellite signal jammer consists of a transmitter and horn antenna. Transmitter shell similar to cable TV on the antenna amplifier, horn antenna at an angle of 45 °, facing the need to interfere with the region, the use of sweeping (3.7GHz ~ 4.2GHz) broadband pulse directional scanning, the implementation of terrestrial transverse interference, so that a particular region of C-band satellite receiving antenna loss of reception or direct damage to the frequency reduction device.
