In order to solve the impact of the interference system on different connected devices and generate a variety of interference patterns, this paper proposes a multi-style vector modulation interference system design. The interference signal generated by the multi-style vector modulation interference device is amplified by power and sent The sub-band antenna, the antenna selects the interference direction under the control of the servo turntable and the control system, implements effective interference to the receiving equipment, reduces economic costs, and meets actual needs. The multi-style vector modulation interference system is composed of interference antenna, power amplifier, servo turntable and control system, communication interference equipment and related accessories. When the system detects the signal, the operating frequency, modulation mode, spectrum width, and other related signal parameters of the interference station are determined through analysis. Then the controller uses the modulator to select the best interference mode and select the frequency to the corresponding position. The high-frequency oscillating signal is used to modulate the interference transmitter, and the interference signal is amplified to the required power by the power amplifier. Finally, the energy is transmitted through the transmitting antenna. The servo turntable is rotated to drive the interference antenna to target the interference object to implement precise interference.
