The core machine generates interference signals of 6 channels according to the interference objects, the signal bandwidth is from 0G to 6G, and the interference frequency band can be flexibly set according to the needs. The 6 channels include 2 DDS (digital frequency synthesis) frequency generation channels and 4 VCO (voltage controlled oscillator) frequency generation channels. The DDS is a direct digital frequency synthesizer. Each channel can set N sections of interference frequencies according to the frequency section of an interference object, namely, N sections of interference frequencies are set according to the acquisition signals of the vehicle-mounted investigation equipment or specific interference signals, and N is a natural number which is determined according to the type of the interfered equipment, the common frequency band and the bearing capacity of hardware resources. Each segment of the interference signal includes a start of frequency, an end of frequency, and an interference time. Meanwhile, the core machine can also set the frequency which needs to be shielded in M sections (depending on the communication frequency band of the vehicle-mounted common communication equipment) according to the radio communication frequency requirement of protecting the vehicle-mounted equipment, and in the interference frequency generation process of 6 channels, the shielding frequency section needs to be avoided, so that the vehicle-mounted interference machine can allow the normal communication frequency of the user to be not interfered while interfering other equipment.
The interference policy binding module is cured in the controller. The vehicle-mounted platform computer downloads information obtained by the vehicle-mounted investigation equipment into the interference strategy binding module through the program control interface, and combines the information into an N-section interference frequency table: each section of interference frequency comprises a frequency starting point, a frequency ending point and interference time, M sections of shielding frequencies are fused, and the M sections of shielding frequencies are downloaded to an interference strategy binding module in interference equipment through a program control interface, so that effective interference can be implemented in a targeted manner at the first time, the optimal efficiency is exerted, and an online dynamic configuration scheme of the interference frequency is achieved.
The power amplifier amplifies the interference signal generated by the core machine to a sufficient power. The power amplifier amplifies 6 paths of signals respectively according to the signals of 6 channels input by the core machine, and the amplification of each path of signal is independent. The link of the core machine with the power amplifier comprises a radio frequency cable and a control cable. The radio frequency cables have 6, each corresponds a transmission passageway. The control cable is used for controlling and monitoring the work of the power amplifier by the core machine or standby, and controlling the output power of the amplifier according to the interference distance. The flexible programmable frequency is combined with the control of the flexible channel amplifier, so that the effect that the jammer can flexibly interfere different objects is achieved.
The first and second integrated antennas are responsible for radiating the transmit signal of the power amplifier to space. The power amplifier sends signals to be connected with the first integrated antenna and the second integrated antenna through two groups of low-loss radio frequency cables. Wherein each group is connected with the integrated antenna by adopting 3 low-loss radio frequency cables. The integrated antenna is arranged in the mobile vehicle-mounted equipment, and an interference signal emitted by the integrated antenna can interfere with electronic equipment signals in a certain range around.
As shown in fig. 2 and 4, the core machine is provided with 6 interference channels in the range of 20MHz to 2700MHz, and the 6 interference channels are respectively an RF1 channel, an RF2 channel, an RF3 channel, an RF4 channel, an RF5 channel and an RF6 channel.

The communication frequency range of the common vehicle-mounted radio station is below 800 MHz. RF1 and RF2 adopt digital control, can accurate dodge communication frequency. The DDS selects a chip with the highest working frequency reaching 3.5GHz, and the model is AD9914. The working clock of the core machine is 2.5GHz, which is enough to be used.

The power amplifier may employ an integral heat dissipation structure. This can result in the radiator of the power amplifier being quite heavy, requiring a large continuous space for installation on the vehicle. The heat dissipation device can be divided into a plurality of parts for heat dissipation, and is convenient to install in a vehicle. In order to save the heat dissipation weight and space, the design of the cooling fin and the inner wall of the vehicle can be considered, the power amplifier is negotiated to be closely attached to the inner wall of the vehicle, and the vehicle body is utilized for heat dissipation.
The signal of the interfering device is transmitted via the omni-directional antenna. The omnidirectional antenna has a frequency range of 20 MHz-6000 MHz. Two antennas, namely an integrated antenna I and an integrated antenna II, are integrated internally. The frequency ranges of the first integrated antenna and the second integrated antenna cover 20 MHz-2000 MHz and 1000 MHz-6000 MHz respectively.
