Detailed description of the invention
Fig. 1 is utility model device modular structure schematic diagram.
Fig. 2 is power supply unit modular structure schematic diagram in the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
As shown in Figure 1, satellite navigation countermeasure set, including appliance stand, antenna and host, is integrated in host and be equipped with communication
Module, signal generator, filter, frequency synthesizer, power supply unit and power amplifier；The communication module, signal occur
Device, filter and power amplifier are connected in series, and are connected with network interface in communication module, and the notebook with upper computer software is logical
It crosses network interface to be connected with communication module, power amplifier connects with antenna, and frequency synthesizer, power supply unit are connected in parallel to signal
On generator.
As shown in Figs. 1-2, satellite navigation countermeasure set, frequency synthesizer by crystal oscillator, phase lock dielectric oscillator, phaselocked loop,
The composition such as amplifier, filter, control circuit, frequency synthesizer provide 2GHz clock signal for signal generator；Filter is
Frequency band is the filter of 1.2GHz~1.6GHz；Power supply unit is by fuse, AC/DC conversion module, DC/DC conversion module
Connect composition with lithium battery, lithium battery output is divided into 24V and turns 28V, 24V and turn 12V and 24V to turn tri- units of 5V；Network interface is standard
232 serial ports.
As shown in Figs. 1-2, the working principle of satellite navigation countermeasure set is as follows: in structure, being made of host and antenna.It
Line is fixed on tripod or turntable, when practical operational exertion, can be born to specified experiment place by individual soldier, be connected and set
Standby, what equipment was implemented is the noise jamming of 1.2GHz~1.6GHz full frequency band.
When needing to implement interference to the specific frequency point between 1.2GHz~1.6GHz, equipment is connected with a cable
The notebook of upper computer software is had with one.The parameter of setting is handed down to letter by the communication module inside equipment by notebook
Number generator, signal generator is resolved to the parameter message to get off is issued, according to resolving as a result, being produced by signal generator
Raw corresponding noise type, frequency point, noise bandwidth etc..Noise type mainly includes narrow-band noise and frequency sweep noise both of which,
It is optional between noise bandwidth 1MHz~50MHz.After signal generator generates corresponding noise, a 1.2GHz of rear class is first passed through
The filter of~1.6GHz filters out the harmonic wave and spuious outside band, guarantees the pure of interference signal.It is sent by filtered signal
Power amplification unit realizes the effect of amplification to the power of interference signal.Amplified signal is by aerial radiation to target area
Domain.
When device power-up, power supply unit in real time passes through the data such as battery data, including electricity, temperature, voltage
Serial ports is sent to signal generator unit, and signal generator unit goes corresponding on control device panel according to obtained electricity data
Battery capacity indication lamp, thus achieve the effect that indicate electricity.If the data exceptions such as cell voltage, temperature, signal generator
It can learn at the first time, to remove the power switch of disconnection power amplifier, protection power amplifier is not damaged.
