Summary of the invention
The purpose of the utility model is to provide a kind of hardware capability can pass through software reconfiguration, the spectrum management jammer of the reconfigurable function of the multiple functions such as signal jammer, GSM/CDMA mobile phone shielding device, the broadcast television signal interference unit that illegally intercuts, accident wireless remote control interference unit that on same hardware platform, can realize taking an examination.
The technical solution that realizes the utility model purpose is:
A kind of spectrum management jammer of reconfigurable function is made up of host computer connected in series successively, network interface chip, dsp chip, fpga chip, high-speed DAC chip, switch filter group, power amplifier, wideband section antenna.
The utility model compared with prior art, its remarkable advantage:
Through system reconfiguration, can implement to disturb to the broadcast singal that cheats at one's exam signal and illegally intercut of arrowband, also can implement to disturb to the GSM/CDMA mobile phone signal in broadband, the TV signal of illegally intercutting; Same hardware platform has been realized the function of multiple jammer; Bring very big facility for the use of radio control department and further improve the efficient of radio safety guarantee, reduce the cost of radio control department buying equipment.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
Fig. 1 is the structural representation of spectrum management jammer of the reconfigurable function of the utility model.
Embodiment
The spectrum management jammer of a kind of reconfigurable function of the utility model is made up of host computer connected in series successively, network interface chip, dsp chip, fpga chip, high-speed DAC chip, switch filter group, power amplifier, wideband section antenna; Network interface chip, dsp chip, fpga chip, high-speed DAC chip, switch filter group, power amplifier link to each other with power supply respectively and are located at jointly in the housing with power supply, and wideband section antenna is located at the outer radio frequency cable that also passes through of housing and is connected with power amplifier; Hardware capability can pass through software reconfiguration; The configuration file stores of FPGA is in host computer, and the difference that host computer is provided with according to the user disturbs the corresponding configuration file of function selecting to be sent to DSP through network interface chip, and DSP receives and resolve the instruction of host computer, is responsible for FPGA is carried out Configuration Online; Wherein the high-speed DAC chip is selected AD9739 for use; The fpga chip Configuration Online is based on that the Network Transmission of IP agreement realizes.
Different interference module can be selected in the user program of the host computer interface that provides convenient operation, and interfering frequency, jamming bandwidth, modulation system can be set, and can be provided with a plurality of target frequencies are implemented to disturb.Host computer is a notebook computer.
The configuration file and the control command of host computer are sent to DSP through network interface chip, and DSP receives and resolve the instruction of host computer, are responsible for FPGA is configured and the parameter setting.
FPGA accomplishes generation, digital modulation, digital filtering, the Digital Up Convert of baseband signal.Produce the interference signal of corresponding interfering frequency, jamming bandwidth, modulation system according to the instruction of host computer.
High-speed DAC converts the digital signal of FPGA to analog signal, and switching rate is 2.5G, and simulation output can cover the whole frequency ranges of 30MHz to 1GHz.
The switch filter group is controlled by DSP, and DSP selects corresponding output filter passage automatically according to the instruction that receives host computer.The output signal of filter is launched by wideband section antenna through after the power amplification.
System forms and comprises that host computer produces two parts with disturbing.Host computer is connected by netting twine with jammer, and transfer of data realizes through the IP agreement.The user program of the host computer interface that provides convenient operation can be provided with interfering frequency, jamming bandwidth, modulation system, and can be provided with a plurality of target frequencies are implemented to disturb.Disturb to produce the instruction that part is received host computer, produce corresponding interference signal, launch by broad-band antenna through filtering, amplification back.Disturb to produce and realize by large-scale F PGA and high-speed DAC.The generation of baseband signal, digital modulation, digital filtering, Digital Up Convert are all integrated in FPGA.The switching rate of high-speed DAC is 2.5G, can cover the whole frequency ranges of 30MHz to 1GHz.FPGA is a programming device; And can Configuration Online; Can select the mechanical, electrical difference in functionality module such as transmitter of looking of mobile phone shielding device, radio control system, voice transmission through the user interface of host computer, to DSP, DSP carries out Configuration Online to FPGA after receiving configuration file to corresponding FPGA configuration file through Network Transmission; Like this, on same hardware platform, can realize different interference functions.
